Members
| ID ↑ | Preferred Label ↑ | Definition ↑ | Date ↑ |
|---|---|---|---|
| Conventions | Conventions | Name of the conventions followed by the dataset. | 2023-03-14 |
| _FillValue | FillValue | A value used to represent missing or undefined data. Allowed for auxiliary coordinate variables but not allowed for coordinate variables. | 2023-03-14 |
| actual_range | actual range | The smallest and the largest valid non-missing values occurring in the variable. | 2023-03-14 |
| add_offset | add offset | If present for a variable, this number is to be added to the data after it is read by an application. If both scale_ factor and add_ offset attributes are present, the data are first scaled before the offset is added. In cases where there is a strong constraint on dataset size, it is allowed to pack the coordinate variables (using add_ offset and/or scale_ factor), but this is not recommended in general. | 2023-03-14 |
| ancillary_variables | ancillary variables | Identifies a variable that contains closely associated data, e.g., the measurement uncertainties of instrument data. | 2023-03-14 |
| axis | axis | Identifies latitude, longitude, vertical, or time axes. | 2023-03-14 |
| bounds | bounds | Identifies a boundary variable. | 2023-03-14 |
| calendar | calendar | Calendar used for encoding time axes. | 2023-03-14 |
| cell_measures | cell measures | Identifies variables that contain cell areas or volumes. | 2023-03-14 |
| cell_methods | cell methods | Records the method used to derive data that represents cell values. | 2023-03-14 |
| cf_role | cf role | Identifies the roles of variables that identify features in discrete sampling geometries | 2023-03-14 |
| climatology | climatology | Identifies a climatology variable. | 2023-03-14 |

| compress | compress | Records dimensions which have been compressed by gathering. | 2023-03-14 |
| computed_standard_name | computed standard name | Indicates the standard name, from the standard name table, of the computed vertical coordinate values, computed according to the formula in the definition. | 2023-03-14 |
| coordinate_interpolation | coordinate interpolation | Indicates that coordinates have been compressed by sampling and identifies the tie point coordinate variables and their associated interpolation variables. | 2023-03-14 |
| coordinates | coordinates | Identifies auxiliary coordinate variables, label variables, and alternate coordinate variables. | 2023-03-14 |
| dimensions | dimensions | Identifies the dimensions that define a domain variable. | 2023-03-14 |
| external_variables | external variables | Identifies variables which are named by cell_ measures attributes in the file but which are not present in the file. | 2023-03-14 |
| featureType | featureType | Specifies the type of discrete sampling geometry to which the data in the scope of this attribute belongs, and implies that all data variables in the scope of this attribute contain collections of features of that type. | 2023-03-14 |
| flag_masks | flag masks | Provides a list of bit fields expressing Boolean or enumerated flags. | 2023-03-14 |
| flag_meanings | flag meanings | Use in conjunction with flag_ values to provide descriptive words or phrases for each flag value. If multi-word phrases are used to describe the flag values, then the words within a phrase should be connected with underscores. | 2023-03-14 |
| flag_values | flag values | Provides a list of the flag values. Use in conjunction with flag_ meanings. | 2023-03-14 |
| formula_terms | formula terms | Identifies variables that correspond to the terms in a formula. | 2023-03-14 |
| geometry | geometry | Identifies a variable that defines geometry. | 2023-03-14 |
| geometry_type | geometry type | Indicates the type of geometry present. | 2023-03-14 |
| grid_mapping | grid mapping | Identifies a variable that defines a grid mapping. | 2023-03-14 |
| history | history | List of the applications that have modified the original data. | 2023-03-14 |
| instance_dimension | instance dimension | An attribute which identifies an index variable and names the instance dimension to which it applies. The index variable indicates that the indexed ragged array representation is being used for a collection of features. | 2023-03-14 |
| institution | institution | Where the original data was produced. | 2023-03-14 |

| leap_month | leap month | Specifies which month is lengthened by a day in leap years for a user defined calendar. | 2023-03-14 |
| leap_year | leap year | Provides an example of a leap year for a user defined calendar. It is assumed that all years that differ from this year by a multiple of four are also leap years. | 2023-03-14 |
