| change_over_time_in_sea_water_absolute_salinity | change over time in sea water absolute salinity | "change_ over_ time_ in_ X" means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate. Absolute Salinity, S_ A, is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the Intergovernmental Oceanographic Commission (IOC). It is the mass fraction of dissolved material in sea water. Absolute Salinity incorporates the spatial variations in the composition of sea water. This type of Absolute Salinity is also called "Density Salinity". TEOS-10 estimates Absolute Salinity as the salinity variable that, when used with the TEOS-10 expression for density, yields the correct density of a sea water sample even when the sample is not of Reference Composition. In practice, Absolute Salinity is often calculated from Practical Salinity using a spatial lookup table of pre-defined values of the Absolute Salinity Anomaly. It is recommended that the version of (TEOS-10) software and the associated Absolute Salinity Anomaly climatology be specified within metadata by attaching a comment attribute to the data variable. Reference: www.teos-10.org; Millero et al., 2008 doi: 10.1016/j.dsr.2007.10.001. There are also standard names for the precisely defined salinity quantities sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 onwards), sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_ water_ salinity. | 2012-04-27 |
| change_over_time_in_sea_water_conservative_temperature | change over time in sea water conservative temperature | The phrase "change_ over_ time_ in_ X" means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate. Conservative Temperature is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the International Oceanographic Commission (IOC). Conservative Temperature is specific potential enthalpy (which has the standard name sea_ water_ specific_ potential_ enthalpy) divided by a fixed value of the specific heat capacity of sea water, namely cp_ 0 = 3991.86795711963 J kg-1 K-1. Conservative Temperature is a more accurate measure of the "heat content" of sea water, by a factor of one hundred, than is potential temperature. Because of this, it can be regarded as being proportional to the heat content of sea water per unit mass.

It is strongly recommended that a variable with this standard name should have the attribute units_ metadata="temperature: difference", meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |
| change_over_time_in_sea_water_density | change over time in sea water density | Sea water density is the in-situ density (not the potential density). If 1000 kg m-3 is subtracted, the standard name "sea_ water_ sigma_ t" should be chosen instead.

| change_over_time_in_sea_water_neutral_density | change over time in sea water neutral density | "change_ over_ time_ in_ X" means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate. "Neutral density" is a variable designed so that a surface of constant neutral density everywhere has a local slope that is close to the local slope of the neutral tangent plane. At the sea surface in the equatorial Pacific neutral density is very close to the potential density anomaly. At other locations, this is not the case. For example, along a neutral density surface there is a difference of up to 0.14 kg/m^3 in the potential density anomaly at the outcrops in the Southern and Northern hemispheres. Refer to Jackett & McDougall (1997; Journal of Physical Oceanography, Vol 27, doi: 10.1175/1520-0485(1997)027<0237:ANDVFT>2.0.CO;2) for more information. | 2011-07-21 |
| change_over_time_in_sea_water_potential_density | change over time in sea water potential density | The phrase "change_ over_ time_ in_ X" means change in a quantity X over a time interval, which should be defined by the bounds of the time coordinate. Sea water potential density is the density a parcel of sea water would have if moved adiabatically to a reference pressure, by default assumed to be sea level pressure. To specify the reference pressure to which the quantity applies, provide a scalar coordinate variable with standard name reference_ pressure. The density of a substance is its mass per unit volume. For sea water potential density, if 1000 kg m-3 is subtracted, the standard name "sea_ water_ sigma_ theta" should be chosen instead. | 2020-02-03 |
| change_over_time_in_sea_water_potential_temperature | change over time in sea water potential temperature | Potential temperature is the temperature a parcel of air or sea water would have if moved adiabatically to sea level pressure.

It is strongly recommended that a variable with this standard name should have the attribute units_ metadata="temperature: difference", meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |
| change_over_time_in_sea_water_practical_salinity | change over time in sea water practical salinity | The phrase "change_ over_ time_ in_ X" means change in a quantity X over a time interval, which should be defined by the bounds of the time coordinate. Practical Salinity, S_ P, is a determination of the salinity of sea water, based on its electrical conductance. The measured conductance, corrected for temperature and pressure, is compared to the conductance of a standard potassium chloride solution, producing a value on the Practical Salinity Scale of 1978 (PSS-78). This name should not be used to describe salinity observations made before 1978, or ones not based on conductance measurements. Conversion of Practical Salinity to other precisely defined salinity measures should use the appropriate formulas specified by TEOS-10. Other standard names for precisely defined salinity quantities are sea_ water_ absolute_ salinity (S_ A); sea_ water_ preformed_ salinity (S_ *), sea_ water_ reference_ salinity (S_ R); sea_ water_ cox_ salinity (S_ C), used for salinity observations between 1967 and 1977; and sea_ water_ knudsen_ salinity (S_ K), used for salinity observations between 1901 and 1966. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_ water_ salinity.

| change_over_time_in_sea_water_preformed_salinity | change over time in sea water preformed salinity | "change_ over_ time_ in_ X" means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate. Preformed Salinity, S*, is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the Intergovernmental Oceanographic Commission (IOC). Preformed Salinity is a salinity variable that is designed to be as conservative as possible, by removing the estimated biogeochemical influences on the sea water composition. Preformed Salinity is Absolute Salinity, S_ A (which has the standard name sea_ water_ absolute_ salinity), minus all contributions to sea water composition from biogeochemical processes. Preformed Salinity is the mass fraction of dissolved material in sea water.

| change_over_time_in_sea_water_salinity | change over time in sea water salinity | "change_ over_ time_ in_ X" means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate. Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &apos;salinity&apos; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 to the present day), sea_ water_ absolute_ salinity, S_ A, sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_ P = (S_ K - 0.03) * (1.80655 / 1.805) and S_ P = S_ C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_ water_ salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_ water_ practical_ salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit "parts per thousand" was used for sea_ water_ knudsen_ salinity and sea_ water_ cox_ salinity. | 2012-04-27 |

The potential enthalpy of a sea water parcel is the specific enthalpy after an adiabatic and isohaline change in pressure from its in situ pressure to the sea pressure p = 0 dbar. "specific" means per unit mass. Reference: www.teos-10.org; McDougall, 2003 doi: 10.1175/1520-0485(2003)033<0945:PEACOV>2.0.CO;2. | 2012-04-27 |
| change_over_time_in_sea_water_temperature | change over time in sea water temperature | "change_ over_ time_ in_ X" means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate.Sea water temperature is the in situ temperature of the sea water. To specify the depth at which the temperature applies use a vertical coordinate variable or scalar coordinate variable. There are standard names for sea_ surface_ temperature, sea_ surface_ skin_ temperature, sea_ surface_ subskin_ temperature and sea_ surface_ foundation_ temperature which can be used to describe data located at the specified surfaces. For observed data, depending on the period during which the observation was made, the measured in situ temperature was recorded against standard "scales". These historical scales include the International Practical Temperature Scale of 1948 (IPTS-48; 1948-1967), the International Practical Temperature Scale of 1968 (IPTS-68, Barber, 1969; 1968-1989) and the International Temperature Scale of 1990 (ITS-90, Saunders 1990; 1990 onwards). Conversion of data between these scales follows t68 = t48 - (4.4 x 10e-6) * t48(100 - t - 48); t90 = 0.99976 * t68. Observations made prior to 1948 (IPTS-48) have not been documented and therefore a conversion cannot be certain. Differences between t90 and t68 can be up to 0.01 at temperatures of 40 C and above; differences of 0.002-0.007 occur across the standard range of ocean temperatures (-10 - 30 C). The International Equation of State of Seawater 1980 (EOS-80, UNESCO, 1981) and the Practical Salinity Scale (PSS-78) were both based on IPTS-68, while the Thermodynamic Equation of Seawater 2010 (TEOS-10) is based on ITS-90.

It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. "Layer" means any layer with upper and lower boundaries that have constant values in some vertical coordinate. There must be a vertical coordinate variable indicating the extent of the layer(s). If the layers are model layers, the vertical coordinate can be model_ level_ number, but it is recommended to specify a physical coordinate (in a scalar or auxiliary coordinate variable) as well.

CDOM plays an important role in the carbon cycling and biogeochemistry of coastal waters. It occurs naturally in aquatic environments primarily as a result of tannins released from decaying plant and animal matter, which can enter coastal areas in river run-off containing organic materials leached from soils. When present in high concentrations, it imparts a brown or yellowish color to water. Its presence can negatively impact fish populations by reducing dissolved oxygen concentrations to harmful levels and by releasing nutrients and metals that contaminate the water. Increased understanding of the role of CDOM will further our ability to manage and protect coastal ecosystems. Sensors are commonly calibrated against a 100 parts per billion (ppb) quinine sulfate dihydrate solution, a fluorescent reference standard commonly used with CDOM sensors. CDOM sensors therefore report in "QSDE" (quinine sulfate dihydrate equivalents). It is important to note, however, that CDOM concentrations in QSDE are not necessarily equivalent to the in situ CDOM concentrations in ppb. | 2016-05-17 |

| convective_cloud_area_fraction_in_atmosphere_layer | convective cloud area fraction in atmosphere layer | "Area fraction" is the fraction of a grid cell's horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_ methods restricts the evaluation to some portion of that grid cell (e.g. "where sea_ ice"), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. "Layer" means any layer with upper and lower boundaries that have constant values in some vertical coordinate. There must be a vertical coordinate variable indicating the extent of the layer(s). If the layers are model layers, the vertical coordinate can be model_ level_ number, but it is recommended to specify a physical coordinate (in a scalar or auxiliary coordinate variable) as well. Standard names referring only to "cloud_ area_ fraction" should be used for quantities for the whole atmosphere column. Standard names also exist for high, medium and low cloud types.

| covariance_over_longitude_of_northward_wind_and_air_temperature | covariance over longitude of northward wind and air temperature | Covariance refers to the sample covariance rather than the population covariance. The quantity with standard name covariance_ over_ longitude_ of_ northward_ wind_ and_ air_ temperature is the covariance of the deviations of meridional air velocity and air temperature about their respective zonal mean values. The data variable must be accompanied by a vertical coordinate variable or scalar coordinate variable and is calculated on an isosurface of that vertical coordinate. "Northward" indicates a vector component which is positive when directed northward (negative southward). Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name "upward_ air_ velocity"). Air temperature is the bulk temperature of the air, not the surface (skin) temperature. It is strongly recommended that a variable with this standard name should have the attribute units_ metadata="temperature: difference", meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |

If the deployment latitude is also the nominal latitude for a discrete geometry (as in Section 9.5 of the CF convention), the deployment latitude should also, or instead, be recorded in a coordinate variable with the standard name of latitude and axis="Y". Latitude is positive northward; its units of "degree_ north" (or equivalent) indicate this explicitly. | 2023-07-05 |
| deployment_longitude | deployment longitude | The longitude of deployment of a station or instrument. The term can be used whenever the deployment position of a station or instrument needs to be supplied along with other types of positions.

If the deployment longitude is also the nominal longitude for a discrete geometry (as in Section 9.5 of the CF convention), the deployment longitude should also, or instead, be recorded in a coordinate variable with the standard name of longitude and axis="X". Longitude is positive eastward; its units of "degree_ east" (or equivalent) indicate this explicitly. | 2023-07-05 |

| depth_at_shallowest_local_minimum_in_vertical_profile_of_mole_concentration_of_dissolved_molecular_oxygen_in_sea_water | depth at shallowest local minimum in vertical profile of mole concentration of dissolved molecular oxygen in sea water | Depth is the vertical distance below the surface. 'Mole concentration' means number of moles per unit volume, also called "molarity", and is used in the construction mole_ concentration_ of_ X_ in_ Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_ expressed_ as_ nitrogen'. The concentration of any chemical species, whether particulate or dissolved, may vary with depth in the ocean. A depth profile may go through one or more local minima in concentration. The depth_ at_ shallowest_ local_ minimum_ in_ vertical_ profile_ of_ mole_ concentration_ of_ dissolved_ molecular_ oxygen_ in_ sea_ water is the depth of the local minimum in the oxygen concentration that occurs closest to the sea surface. | 2010-05-12 |
| depth_below_geoid | depth below geoid | The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. (The volume enclosed between the geoid and the sea floor equals the mean volume of water in the ocean). In an ocean GCM the geoid is the surface of zero depth, or the rigid lid if the model uses that approximation. To specify which geoid or geopotential datum is being used as a reference level, a grid_ mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention.

Dew point temperature is the temperature at which a parcel of air reaches saturation upon being cooled at constant pressure and specific humidity. It is strongly recommended that a variable with this standard name should have the attribute units_ metadata="temperature: difference", meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |
| dew_point_temperature | dew point temperature | Dew point temperature is the temperature at which a parcel of air reaches saturation upon being cooled at constant pressure and specific humidity. It is strongly recommended that a variable with this standard name should have a units_ metadata attribute, with one of the values "on-scale" or "difference", whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |

"Ambient_ aerosol" means that the aerosol is measured or modelled at the ambient state of pressure, temperature and relative humidity that exists in its immediate environment. "Ambient aerosol particles" are aerosol particles that have taken up ambient water through hygroscopic growth. The extent of hygroscopic growth depends on the relative humidity and the composition of the particles. To specify the relative humidity and temperature at which the quantity described by the standard name applies, provide scalar coordinate variables with standard names of "relative_ humidity" and "air_ temperature". | 2019-05-14 |

This diurnal warm layer, caused by absorption of solar radiation in the absence of strong mixing, together with a cool skin effect, account for the total temperature difference between the sea_ surface_ skin_ temperature and the sea_ surface_ foundation_ temperature. The cool skin effect is associated with the turbulent and infrared radiative heat loss at the air-sea interface.

| difference_between_sea_surface_temperature_and_air_temperature | difference between sea surface temperature and air temperature | Sea surface temperature is usually abbreviated as "SST". It is the temperature of sea water near the surface (including the part under sea-ice, if any), not the skin or interface temperature, whose standard names are sea_ surface_ skin_ temperature and surface_ temperature, respectively. For the temperature of sea water at a particular depth or layer, a data variable of "sea_ water_ temperature" with a vertical coordinate axis should be used. Air temperature is the bulk temperature of the air, not the surface (skin) temperature. It is strongly recommended that a variable with this standard name should have the attribute units_ metadata="temperature: difference", meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |
| difference_of_air_pressure_from_model_reference | difference of air pressure from model reference | In some atmosphere models, the difference of air pressure from model reference is a prognostic variable, instead of the air pressure itself.

| direction_of_sea_ice_displacement | direction of sea ice displacement | The phrase "direction_ of_ X" means direction of a vector, a bearing. "Displacement" means the change in geospatial position of an object that has moved over time. If possible, the time interval over which the motion took place should be specified using a bounds variable for the time coordinate variable. A displacement can be represented as a vector. Such a vector should however not be interpreted as describing a rectilinear, constant speed motion but merely as an indication that the start point of the vector is found at the tip of the vector after the time interval associated with the displacement variable. A displacement does not prescribe a trajectory. Sea ice displacement can be defined as a two-dimensional vector, with no vertical component. In that case, "displacement" is also the distance across the earth's surface calculated from the change in a moving object's geospatial position between the start and end of the time interval associated with the displacement variable.

A data variable containing the area affected by fire should be given the standard name fire_ area. It is strongly recommended that a variable with this standard name should have a units_ metadata attribute, with one of the values "on-scale" or "difference", whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |

| fraction_of_surface_downwelling_photosynthetic_radiative_flux_absorbed_by_vegetation | fraction of surface downwelling photosynthetic radiative flux absorbed by vegetation | Downwelling radiation is radiation from above. It does not mean "net downward". The sign convention is that "upwelling" is positive upwards and "downwelling" is positive downwards. The surface called "surface" means the lower boundary of the atmosphere. The quantity with standard name fraction_ of_ surface_ downwelling_ photosynthetic_ radiative_ flux_ absorbed_ by_ vegetation, often called Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), is the fraction of incoming solar radiation in the photosynthetically active radiation spectral region that is absorbed by a vegetation canopy. "Photosynthetic" radiation is the part of the spectrum which is used in photosynthesis e.g. 400-700 nm. The range of wavelengths could be specified precisely by the bounds of a coordinate of "radiation_ wavelength". When thought of as being incident on a surface, a radiative flux is sometimes called "irradiance". In addition, it is identical with the quantity measured by a cosine-collector light-meter and sometimes called "vector irradiance". In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. "Vegetation" means any plants e.g. trees, shrubs, grass. The term "plants" refers to the kingdom of plants in the modern classification which excludes fungi.

For observed data, depending on the period during which the observation was made, the measured in situ temperature was recorded against standard "scales". These historical scales include the International Practical Temperature Scale of 1948 (IPTS-48; 1948-1967), the International Practical Temperature Scale of 1968 (IPTS-68, Barber, 1969; 1968-1989) and the International Temperature Scale of 1990 (ITS-90, Saunders 1990; 1990 onwards). Conversion of data between these scales follows t68 = t48 - (4.4 x 10e-6) * t48(100 - t - 48); t90 = 0.99976 * t68. Observations made prior to 1948 (IPTS-48) have not been documented and therefore a conversion cannot be certain. Differences between t90 and t68 can be up to 0.01 at temperatures of 40 C and above; differences of 0.002-0.007 occur across the standard range of ocean temperatures (-10 - 30 C). The International Equation of State of Seawater 1980 (EOS-80, UNESCO, 1981) and the Practical Salinity Scale (PSS-78) were both based on IPTS-68, while the Thermodynamic Equation of Seawater 2010 (TEOS-10) is based on ITS-90.

Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term 'salinity' is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 to the present day), sea_ water_ absolute_ salinity, S_ A, sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows S_ P = (S_ K - 0.03) * (1.80655 / 1.805) and S_ P = S_ C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_ water_ salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_ water_ practical_ salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. Practical salinity units are dimensionless.

| isccp_cloud_area_fraction | isccp cloud area fraction | "Area fraction" is the fraction of a grid cell's horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_ methods restricts the evaluation to some portion of that grid cell (e.g. "where sea_ ice"), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. The cloud area fraction is for the whole atmosphere column, as seen from the surface or the top of the atmosphere. For the cloud area fraction between specified levels in the atmosphere, standard names including "cloud_ area_ fraction_ in_ atmosphere_ layer" are used. Standard names also exist for high, medium and low cloud types. The ISCCP cloud area fraction is diagnosed from atmosphere model output by the ISCCP simulator software in such a way as to be comparable with the observational diagnostics of ISCCP (the International Satellite Cloud Climatology Project). Cloud area fraction is also called "cloud amount" and "cloud cover". | 2024-09-04 |

The scale is open ended which allows the range of numbers to adequately define fire problems, even in time of low to moderate fire danger. Computed BI values represent the near upper limit to be expected on the rating area. In other words, if a fire occurs in the worst fuel, weather and topography conditions of the rating area, these numbers indicate its expected fire line intensities and flame length.

A coordinate variable of harmonic_ period should be used to specify the period of the sinusoidal wave. Because global average sea level change quantifies the change in volume of the world ocean, it is not calculated necessarily by considering local changes in mean sea level. | 2017-07-24 |

| probability_distribution_of_wind_from_direction_over_time | probability distribution of wind from direction over time | The construction "probability_ distribution_ of_ X_ over_ Z" means that the data variable is a number in the range 0.0-1.0 for each range of X, where X varies over Z. The data variable should have an axis for X. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name "upward_ air_ velocity"). The phrase "from_ direction" is used in the construction X_ from_ direction and indicates the direction from which the velocity vector of X is coming. The direction is a bearing in the usual geographical sense, measured positive clockwise from due north. In meteorological reports, the direction of the wind vector is usually (but not always) given as the direction from which it is blowing ("wind_ from_ direction") (westerly, northerly, etc.). In other contexts, such as atmospheric modelling, it is often natural to give the direction in the usual manner of vectors as the heading or the direction to which it is blowing ("wind_ to_ direction") (eastward, southward, etc.). | 2020-03-09 |

| product_of_eastward_sea_water_velocity_and_salinity | product of eastward sea water velocity and salinity | "product_ of_ X_ and_ Y" means X*Y. A velocity is a vector quantity. "Eastward" indicates a vector component which is positive when directed eastward (negative westward). Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &apos;salinity&apos; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and normally given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 to the present day), sea_ water_ absolute_ salinity, S_ A, sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_ P = (S_ K - 0.03) * (1.80655 / 1.805) and S_ P = S_ C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_ water_ salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_ water_ practical_ salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit "parts per thousand" was used for sea_ water_ knudsen_ salinity and sea_ water_ cox_ salinity. | 2012-04-27 |

Air pressure is the force per unit area which would be exerted when the moving gas molecules of which the air is composed strike a theoretical surface of any orientation. "Specific" means per unit mass. Specific humidity is the mass fraction of water vapor in (moist) air. | 2019-06-17 |
| product_of_northward_sea_water_velocity_and_salinity | product of northward sea water velocity and salinity | "product_ of_ X_ and_ Y" means X*Y. A velocity is a vector quantity. "Northward" indicates a vector component which is positive when directed northward (negative southward). Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &apos;salinity&apos; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and normally given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 to the present day), sea_ water_ absolute_ salinity, S_ A, sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_ P = (S_ K - 0.03) * (1.80655 / 1.805) and S_ P = S_ C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_ water_ salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_ water_ practical_ salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit "parts per thousand" was used for sea_ water_ knudsen_ salinity and sea_ water_ cox_ salinity. | 2012-04-27 |

Potential temperature is the temperature a parcel of air or sea water would have if moved adiabatically to sea level pressure. The phrase "ratio_ of_ X_ to_ Y" means X/Y. The term "anomaly" means difference from climatology. It is strongly recommended that a variable with this standard name should have the attribute units_ metadata="temperature: difference", meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |

The phrase "ratio_ of_ X_ to_ Y" means X/Y. The term "anomaly" means difference from climatology. Practical Salinity, S_ P, is a determination of the salinity of sea water, based on its electrical conductance. The measured conductance, corrected for temperature and pressure, is compared to the conductance of a standard potassium chloride solution, producing a value on the Practical Salinity Scale of 1978 (PSS-78). This name should not be used to describe salinity observations made before 1978, or ones not based on conductance measurements. Conversion of Practical Salinity to other precisely defined salinity measures should use the appropriate formulas specified by TEOS-10. Other standard names for precisely defined salinity quantities are sea_ water_ absolute_ salinity (S_ A); sea_ water_ preformed_ salinity (S_ *), sea_ water_ reference_ salinity (S_ R); sea_ water_ cox_ salinity (S_ C), used for salinity observations between 1967 and 1977; and sea_ water_ knudsen_ salinity (S_ K), used for salinity observations between 1901 and 1966. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_ water_ salinity.

| sea_ice_area_fraction | sea ice area fraction | "Area fraction" is the fraction of a grid cell's horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_ methods restricts the evaluation to some portion of that grid cell (e.g. "where sea_ ice"), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. Sea ice area fraction is area of the sea surface occupied by sea ice. It is also called "sea ice concentration".

A displacement does not prescribe a trajectory. Sea ice displacement can be defined as a two-dimensional vector, with no vertical component. In that case, "displacement" is also the distance across the earth's surface calculated from the change in a moving object's geospatial position between the start and end of the time interval associated with the displacement variable. | 2010-07-26 |

"Sea ice" means all ice floating in the sea which has formed from freezing sea water, rather than by other processes such as calving of land ice to form icebergs. Sea-ice algae (or simply 'ice algae' when the context of sea ice is clear) refer to algae uniquely able to thrive within the sea-ice environment. This distinction from phytoplankton is essential, as several phytoplankton species that become trapped in sea ice eventually perish due to a lack of genetic adaptation or acclimation strategies to survive such conditions. By referring to 'sea-ice algae,' we highlight these algae's specific features and ecological significance within the sea-ice habitat. Chlorophylls are the green pigments found in most plants, algae and cyanobacteria; their presence is essential for photosynthesis to take place. There are several different forms of chlorophyll that occur naturally. All contain a chlorin ring (chemical formula C20H16N4) which gives the green pigment and a side chain whose structure varies. The naturally occurring forms of chlorophyll contain between 35 and 55 carbon atoms. | 2024-11-11 |

| sea_surface_foundation_temperature | sea surface foundation temperature | The sea surface foundation temperature is the water temperature that is not influenced by a thermally stratified layer of diurnal temperature variability (either by daytime warming or nocturnal cooling). The foundation temperature is named to indicate that it is the temperature from which the growth of the diurnal thermocline develops each day, noting that on some occasions with a deep mixed layer there is no clear foundation temperature in the surface layer. In general, sea surface foundation temperature will be similar to a night time minimum or pre-dawn value at depths of between approximately 1 and 5 meters. In the absence of any diurnal signal, the foundation temperature is considered equivalent to the quantity with standard name sea_ surface_ subskin_ temperature. The sea surface foundation temperature defines a level in the upper water column that varies in depth, space, and time depending on the local balance between thermal stratification and turbulent energy and is expected to change slowly over the course of a day. If possible, a data variable with the standard name sea_ surface_ foundation_ temperature should be used with a scalar vertical coordinate variable to specify the depth of the foundation level. Sea surface foundation temperature is measured at the base of the diurnal thermocline or as close to the water surface as possible in the absence of thermal stratification. Only in situ contact thermometry is able to measure the sea surface foundation temperature. Analysis procedures must be used to estimate sea surface foundation temperature value from radiometric satellite measurements of the quantities with standard names sea_ surface_ skin_ temperature and sea_ surface_ subskin_ temperature. Sea surface foundation temperature provides a connection with the historical concept of a "bulk" sea surface temperature considered representative of the oceanic mixed layer temperature that is typically represented by any sea temperature measurement within the upper ocean over a depth range of 1 to approximately 20 meters. The general term, "bulk" sea surface temperature, has the standard name sea_ surface_ temperature with no associated vertical coordinate axis. Sea surface foundation temperature provides a more precise, well defined quantity than "bulk" sea surface temperature and, consequently, is more representative of the mixed layer temperature. The temperature of sea water at a particular depth (other than the foundation level) should be reported using the standard name sea_ water_ temperature and, wherever possible, supplying a vertical coordinate axis or scalar coordinate variable. It is strongly recommended that a variable with this standard name should have a units_ metadata attribute, with one of the values "on-scale" or "difference", whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |

| sea_surface_salinity | sea surface salinity | Sea surface salinity is the salt content of sea water close to the sea surface, often on the Practical Salinity Scale of 1978. However, the unqualified term &apos;salinity&apos; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. Sea surface salinity is often abbreviated as "SSS". For the salinity of sea water at a particular depth or layer, a data variable of "sea_ water_ salinity" or one of the more precisely defined salinities should be used with a vertical coordinate axis. There are standard names for the precisely defined salinity quantities: sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 to the present day), sea_ water_ absolute_ salinity, S_ A, sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_ P = (S_ K - 0.03) * (1.80655 / 1.805) and S_ P = S_ C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_ water_ salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_ water_ practical_ salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit "parts per thousand" was used for sea_ water_ knudsen_ salinity and sea_ water_ cox_ salinity. | 2012-04-27 |

It is the mass fraction of dissolved material in sea water. Absolute Salinity incorporates the spatial variations in the composition of sea water. This type of Absolute Salinity is also called "Density Salinity". TEOS-10 estimates Absolute Salinity as the salinity variable that, when used with the TEOS-10 expression for density, yields the correct density of a sea water sample even when the sample is not of Reference Composition. In practice, Absolute Salinity is often calculated from Practical Salinity using a spatial lookup table of pre-defined values of the Absolute Salinity Anomaly. It is recommended that the version of (TEOS-10) software and the associated Absolute Salinity Anomaly climatology be specified within metadata by attaching a comment attribute to the data variable. Reference: www.teos-10.org; Millero et al., 2008 doi: 10.1016/j.dsr.2007.10.001.

The passive tracer is transported within the ocean as if it were conservative temperature. The passive tracer is zero in the control climate of the model. The passive tracer records added heat, as described for the CMIP6 FAFMIP experiment (doi:10.5194/gmd-9-3993-2016), following earlier ideas. Conservative Temperature is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the International Oceanographic Commission (IOC).

| sea_water_cox_salinity | sea water cox salinity | Cox Salinity, S_ C, is defined unitless as a mass fraction per mil (0/00) or "parts per thousand". S_ C was the standard salinity measure from 1967 until Practical Salinity, S_ P, was established with PSS-78 (1978). Chlorinity, Cl, is calculated from the conductivity of a sea water sample and since the work of the Joint Panel for Oceanographic Tables and Standards (JPOTS; 1966) is converted into Cox Salinity using S_ C = 1.80655Cl. This type of salinity was called simply "salinity" from 1967 to 1978. Cox Salinity was replaced by Practical Salinity in 1978. Cox Salinity is converted to Practical Salinity following S_ P = S_ C, however the accuracy of this is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of the Practical Salinity Scale 1978 (PSS-78).

| sea_water_knudsen_salinity | sea water knudsen salinity | Knudsen Salinity, S_ K, is defined unitless as a mass fraction per mil (0/00) or "parts per thousand", and was calculated from the titration of inorganic salts from a sample of sea water after a commission to study the problem of determining salinity and density was initiated by the International Council for the Exploration of the Sea (ICES) in 1899. S_ K was the standard salinity measure until S_ C (Cox Salinity) was established in 1967. Since the work of Knudsen (1901), chlorinity is converted into Knudsen Salinity using S_ K = 0.030 + 1.805 Cl. This type of salinity was called simply "salinity" from 1901 to 1966. From the 1960s on, electrical conductivity began to be used to estimate the Knudsen Salinity, rather than chemical titration. Knudsen Salinity was replaced by Cox Salinity in 1967 which was in turn replaced by Practical Salinity, S_ P, in 1978. Conversion of Knudsen Salinity to Practical Salinity follows S_ P = (S_ K - 0.03) * (1.80655 / 1.805).

If used for a layer heat content, coordinate bounds should be used to define the extent of the layers. If no coordinate bounds are specified, it is assumed that the integral is calculated over the entire vertical extent of the medium, e.g, if the medium is sea water the integral is assumed to be calculated over the full depth of the ocean.

The measured conductance, corrected for temperature and pressure, is compared to the conductance of a standard potassium chloride solution, producing a value on the Practical Salinity Scale of 1978 (PSS-78). This name should not be used to describe salinity observations made before 1978, or ones not based on conductance measurements. Conversion of Practical Salinity to other precisely defined salinity measures should use the appropriate formulas specified by TEOS-10.

| sea_water_practical_salinity_at_sea_floor | sea water practical salinity at sea floor | The practical salinity at the sea floor is that adjacent to the ocean bottom, which would be the deepest grid cell in an ocean model and within the benthic boundary layer for measurements. Practical Salinity, S_ P, is a determination of the salinity of sea water, based on its electrical conductance. The measured conductance, corrected for temperature and pressure, is compared to the conductance of a standard potassium chloride solution, producing a value on the Practical Salinity Scale of 1978 (PSS-78). This name should not be used to describe salinity observations made before 1978, or ones not based on conductance measurements.

| sea_water_preformed_alkalinity_expressed_as_mole_equivalent | sea water preformed alkalinity expressed as mole equivalent | "Mole concentration" means the number of moles per unit volume, also called "molarity", and is used in the construction "mole_ concentration_ of_ X_ in_ Y", where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_ expressed_ as_ nitrogen". "Alkalinity" refers to total alkalinity equivalent concentration, including carbonate, borate, phosphorus, silicon, and nitrogen components. The subduction and subsequent transport of surface water carry into the interior ocean considerable quantities of alkalinity, which is entirely independent of biological activity (such as organic decomposition and oxidation) after the water leaves the sea surface. Such alkalinity is termed "preformed" alkalinity (Redfield,1942). | 2024-05-20 |
| sea_water_preformed_salinity | sea water preformed salinity | Preformed Salinity, S*, is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the Intergovernmental Oceanographic Commission (IOC). Preformed Salinity is a salinity variable that is designed to be as conservative as possible, by removing the estimated biogeochemical influences on the sea water composition. Preformed Salinity is Absolute Salinity, S_ A (which has the standard name sea_ water_ absolute_ salinity), minus all contributions to sea water composition from biogeochemical processes. Preformed Salinity is the mass fraction of dissolved material in sea water.

There are also standard names for the precisely defined salinity quantities sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 onwards), and sea_ water_ reference_ salinity.

| sea_water_pressure | sea water pressure | "Sea water pressure" is the pressure that exists in the medium of sea water. It includes the pressure due to overlying sea water, sea ice, air and any other medium that may be present.

| sea_water_redistributed_conservative_temperature | sea water redistributed conservative temperature | The quantity with standard name sea_ water_ redistributed_ conservative_ temperature is a passive tracer in an ocean model which is subject to an externally imposed perturbative surface heat flux. The passive tracer is initialised to the conservative temperature in the control climate before the perturbation is imposed. Its surface flux is the heat flux from the atmosphere, not including the imposed perturbation, and is converted to a passive tracer increment as if it were being added to conservative temperature. The passive tracer is transported within the ocean as if it were conservative temperature. The passive tracer records redistributed heat, as described for the CMIP6 FAFMIP experiment (doi:10.5194/gmd-9-3993-2016), following earlier ideas. Conservative Temperature is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the International Oceanographic Commission (IOC). Conservative Temperature is specific potential enthalpy (which has the standard name sea_ water_ specific_ potential_ enthalpy) divided by a fixed value of the specific heat capacity of sea water, namely cp_ 0 = 3991.86795711963 J kg-1 K-1. Conservative Temperature is a more accurate measure of the "heat content" of sea water, by a factor of one hundred, than is potential temperature. Because of this, it can be regarded as being proportional to the heat content of sea water per unit mass.

| sea_water_reference_salinity | sea water reference salinity | If a sea water sample has the Reference Composition (defined in Millero et al., 2008), then its Reference Salinity is the best available estimate of its Absolute Salinity. For general purposes, Reference Salinity is (35.16504 g kg-1)/35 times Practical Salinity. Reference: www.teos-10.org; Millero et al., 2008 doi: 10.1016/j.dsr.2007.10.001.

| sea_water_salinity | sea water salinity | Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &apos;salinity&apos; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 to the present day), sea_ water_ absolute_ salinity, S_ A, sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_ P = (S_ K - 0.03) * (1.80655 / 1.805) and S_ P = S_ C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_ water_ salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_ water_ practical_ salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit "parts per thousand" was used for sea_ water_ knudsen_ salinity and sea_ water_ cox_ salinity. | 2012-04-27 |

"Ekman drift" is the movement of a layer of water (the Ekman layer) due to the combination of wind stress at the sea surface and the Coriolis effect. Ekman drift is to the right of the wind direction in the Northern Hemisphere and the left in the Southern Hemisphere.

| sea_water_temperature | sea water temperature | Sea water temperature is the in situ temperature of the sea water. To specify the depth at which the temperature applies use a vertical coordinate variable or scalar coordinate variable. There are standard names for sea_ surface_ temperature, sea_ surface_ skin_ temperature, sea_ surface_ subskin_ temperature and sea_ surface_ foundation_ temperature which can be used to describe data located at the specified surfaces. For observed data, depending on the period during which the observation was made, the measured in situ temperature was recorded against standard "scales". These historical scales include the International Practical Temperature Scale of 1948 (IPTS-48; 1948-1967), the International Practical Temperature Scale of 1968 (IPTS-68, Barber, 1969; 1968-1989) and the International Temperature Scale of 1990 (ITS-90, Saunders 1990; 1990 onwards). Conversion of data between these scales follows t68 = t48 - (4.4 x 10e-6) * t48(100 - t - 48); t90 = 0.99976 * t68. Observations made prior to 1948 (IPTS-48) have not been documented and therefore a conversion cannot be certain. Differences between t90 and t68 can be up to 0.01 at temperatures of 40 C and above; differences of 0.002-0.007 occur across the standard range of ocean temperatures (-10 - 30 C). The International Equation of State of Seawater 1980 (EOS-80, UNESCO, 1981) and the Practical Salinity Scale (PSS-78) were both based on IPTS-68, while the Thermodynamic Equation of Seawater 2010 (TEOS-10) is based on ITS-90.

| square_of_sea_surface_height_above_geoid | square of sea surface height above geoid | The phrase "square_ of_ X" means X*X. "Height_ above_ X" means the vertical distance above the named surface X. "Sea surface height" is a time-varying quantity. The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. (The volume enclosed between the geoid and the sea floor equals the mean volume of water in the ocean). In an ocean GCM the geoid is the surface of zero depth, or the rigid lid if the model uses that approximation. To specify which geoid or geopotential datum is being used as a reference level, a grid_ mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention. By definition of the geoid, the global average of the time-mean sea surface height (i.e. mean sea level) above the geoid must be zero. | 2017-07-24 |
| square_of_sea_surface_salinity | square of sea surface salinity | The phrase "square_ of_ X" means X*X. Sea surface salinity is the salt concentration of sea water close to the sea surface, often on the Practical Salinity Scale of 1978. However, the unqualified term 'salinity' is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. Sea surface salinity is often abbreviated as "SSS". For the salinity of sea water at a particular depth or layer, a data variable of "sea_ water_ salinity" or one of the more precisely defined salinities should be used with a vertical coordinate axis. There are standard names for the precisely defined salinity quantities: sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 to the present day), sea_ water_ absolute_ salinity, S_ A, sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_ P = (S_ K - 0.03) * (1.80655 / 1.805) and S_ P = S_ C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_ water_ salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_ water_ practical_ salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit "parts per thousand" was used for sea_ water_ knudsen_ salinity and sea_ water_ cox_ salinity. | 2018-04-16 |
| square_of_sea_surface_temperature | square of sea surface temperature | Sea surface temperature is usually abbreviated as "SST". It is the temperature of sea water near the surface (including the part under sea-ice, if any), and not the skin temperature, whose standard name is surface_ temperature. For the temperature of sea water at a particular depth or layer, a data variable of sea_ water_ temperature with a vertical coordinate axis should be used. "square_ of_ X" means X*X. It is strongly recommended that a variable with this standard name should have a units_ metadata attribute, with one of the values "on-scale" or "difference", whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units). | 2024-05-20 |

| stagnation_temperature_in_air | stagnation temperature in air | In thermodynamics and fluid mechanics, stagnation temperature is the temperature at a stagnation point in a fluid flow. At a stagnation point the speed of the fluid is zero and all of the kinetic energy has been converted to internal energy and is added to the local static enthalpy. In both compressible and incompressible fluid flow, the stagnation temperature is equal to the total temperature at all points on the streamline leading to the stagnation point. In aviation, stagnation temperature is known as total air temperature and is measured by a temperature probe mounted on the surface of the aircraft. The probe is designed to bring the air to rest relative to the aircraft. As the air is brought to rest, kinetic energy is converted to internal energy. The air is compressed and experiences an adiabatic increase in temperature. Therefore, total air temperature is higher than the static (or ambient) air temperature. Total air temperature is an essential input to an air data computer in order to enable computation of static air temperature and hence true airspeed.

Conservative Temperature is specific potential enthalpy (which has the standard name sea_ water_ specific_ potential_ enthalpy) divided by a fixed value of the specific heat capacity of sea water, namely cp_ 0 = 3991.86795711963 J kg-1 K-1. Conservative Temperature is a more accurate measure of the "heat content" of sea water, by a factor of one hundred, than is potential temperature.

Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978.

The units of salinity are dimensionless and normally given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 to the present day), sea_ water_ absolute_ salinity, S_ A, sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_ P = (S_ K - 0.03) * (1.80655 / 1.805) and S_ P = S_ C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of PSS-78.

There are standard names for the more precisely defined salinity quantities: sea_ water_ knudsen_ salinity, S_ K (used for salinity observations between 1901 and 1966), sea_ water_ cox_ salinity, S_ C (used for salinity observations between 1967 and 1977), sea_ water_ practical_ salinity, S_ P (used for salinity observations from 1978 to the present day), sea_ water_ absolute_ salinity, S_ A, sea_ water_ preformed_ salinity, S_ *, and sea_ water_ reference_ salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_ P = (S_ K - 0.03) * (1.80655 / 1.805) and S_ P = S_ C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_ C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_ water_ salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_ water_ practical_ salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit "parts per thousand" was used for sea_ water_ knudsen_ salinity and sea_ water_ cox_ salinity. The specification of a physical process by the phrase due_ to_ process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. "Sea ice thermodynamics" refers to the addition or subtraction of sea ice mass due to surface and basal fluxes, i.e. due to melting, sublimation and fusion. "Sea ice" means all ice floating in the sea which has formed from freezing sea water, rather than by other processes such as calving of land ice to form icebergs. | 2018-07-03 |

| tendency_of_sea_water_temperature | tendency of sea water temperature | The phrase "tendency_ of_ X" means derivative of X with respect to time. Sea water temperature is the in situ temperature of the sea water. For observed data, depending on the period during which the observation was made, the measured in situ temperature was recorded against standard "scales". These historical scales include the International Practical Temperature Scale of 1948 (IPTS-48; 1948-1967), the International Practical Temperature Scale of 1968 (IPTS-68, Barber, 1969; 1968-1989) and the International Temperature Scale of 1990 (ITS-90, Saunders 1990; 1990 onwards). Conversion of data between these scales follows t68 = t48 - (4.4 x 10e-6) * t48(100 - t - 48); t90 = 0.99976 * t68. Observations made prior to 1948 (IPTS-48) have not been documented and therefore a conversion cannot be certain. Differences between t90 and t68 can be up to 0.01 at temperatures of 40 C and above; differences of 0.002-0.007 occur across the standard range of ocean temperatures (-10 - 30 C). The International Equation of State of Seawater 1980 (EOS-80, UNESCO, 1981) and the Practical Salinity Scale (PSS-78) were both based on IPTS-68, while the Thermodynamic Equation of Seawater 2010 (TEOS-10) is based on ITS-90.

| x_heat_flux_in_sea_water_due_to_advection | x heat flux in sea water due to advection | "x" indicates a vector component along the grid x-axis, positive with increasing x. The specification of a physical process by the phrase due_ to_ process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. | 2013-06-27 |
| x_sea_water_velocity | x sea water velocity DEPRECATED | A velocity is a vector quantity. 'x' indicates a vector component along the grid x-axis, when this is not true longitude, positive with increasing x. | 2006-09-26 |
| x_wind | x wind | "x" indicates a vector component along the grid x-axis, positive with increasing x. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_ air_ velocity.) | 2013-01-11 |
| x_wind_gust | x wind gust | "x" indicates a vector component along the grid x-axis, positive with increasing x. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_ air_ velocity.) A gust is a sudden brief period of high wind speed. In an observed timeseries of wind speed, the gust wind speed can be indicated by a cell_ methods of maximum for the time-interval. In an atmospheric model which has a parametrised calculation of gustiness, the gust wind speed may be separately diagnosed from the wind speed. | 2017-11-28 |
| y_derivative_of_ocean_rigid_lid_pressure | y derivative of ocean rigid lid pressure | "component_ derivative_ of_ X" means the derivative of X with respect to distance in the component direction, which may be northward, southward, eastward, westward, x or y. The last two indicate derivatives along the axes of the grid, whether or not they are true longitude and latitude. y_ derivative_ of_ ocean_ rigid_ lid_ pressure means (d/dy) of the ocean surface pressure, as derived by a rigid lid approximation, keeping the other horizontal coordinate (x, presumably) constant. | 2013-01-11 |
| y_heat_flux_in_sea_water_due_to_advection | y heat flux in sea water due to advection | "y" indicates a vector component along the grid y-axis, positive with increasing y.
