Its integral with respect to time is often called after its units of "degree-days". The air_ temperature variable, which is the data variable of the integral should have a scalar coordinate variable or a size-one coordinate variable with the standard name of air_ temperature_ threshold, to indicate the threshold. | 2017-11-28 |

| 7701XKQN | integral of sea water practical salinity wrt depth DEPRECATED | "integral_ of_ Y_ wrt_ X" means int Y dX. The data variable should have an axis for X specifying the limits of the integral as bounds. "wrt" means with respect to. Depth is the vertical distance below the surface. 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.

| CFSN0610 | integral of sea water temperature wrt depth in ocean layer DEPRECATED | "integral_ of_ Y_ wrt_ X" means int Y dX. The data variable should have an axis for X specifying the limits of the integral as bounds. "wrt" means with respect to. "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. Depth is the vertical distance below the surface. 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.

| R7ACY32S | integral wrt depth of product of sea water density and conservative temperature DEPRECATED | The phrase "integral_ wrt_ X_ of_ Y" means int Y dX. To specify the limits of the integral the data variable should have an axis for X and associated coordinate bounds. If no axis for X is associated with the data variable, or 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 air the integral is assumed to be calculated over the full depth of the atmosphere. The phrase "wrt" means "with respect to". Depth is the vertical distance below the surface. The phrase "product_ of_ X_ and_ Y" means X*Y. Sea water density is the in-situ density (not the potential density). For Boussinesq models, density is the constant Boussinesq reference density, a quantity which has the standard name reference_ sea_ water_ density_ for_ boussinesq_ approximation. 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.

| DVS70CTS | integral wrt depth of product of sea water density and salinity DEPRECATED | The phrase "integral_ wrt_ X_ of_ Y" means int Y dX. To specify the limits of the integral the data variable should have an axis for X and associated coordinate bounds. If no axis for X is associated with the data variable, or 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 air the integral is assumed to be calculated over the full depth of the atmosphere. The phrase "wrt" means "with respect to". The phrase "product_ of_ X_ and_ Y" means X*Y. Depth is the vertical distance below the surface. Sea water density is the in-situ density (not the potential density). For Boussinesq models, density is the constant Boussinesq reference density, a quantity which has the standard name reference_ sea_ water_ density_ for_ boussinesq_ approximation. 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. The unit "parts per thousand" was used for sea_ water_ knudsen_ salinity and sea_ water_ cox_ salinity. | 2019-10-14 |

| V3NLUKPK | tendency of sea water conservative temperature expressed as heat content due to parameterized eddy dianeutral mixing DEPRECATED | The phrase "tendency_ of_ X" means derivative of X with respect to time. The phrase "expressed_ as_ heat_ content" means that this quantity is calculated as the specific heat capacity times density of sea water multiplied by the conservative temperature of the sea water in the grid cell and integrated over depth. 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. 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.

| CFV8N122 | tendency of sea water salinity due to bolus advection DEPRECATED | "tendency_ of_ X" means derivative of X with respect to time.

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 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. | 2017-11-28 |

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 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.
