The variable naming follows the principles given in the actual NetCDF Climate and Forecast (CF) Metadata Conventions version as far as possible. This especially means that the definition of the coordinate arrays and data arrays bases on this standard. For many variables, an attribute standard_name, a name and applicable units are defined there, as well as representations of coordinate systems. However, since
it was developed for model data, not all observational data are covered. This especially means that
we cannot provide the standardized name and attribute standard_name for all variables. For those variables a special long_name is mandatory instead of standard_name.
On these pages you can find a list of variables sorted according variable abbreviation or CF-Standard_name /long_name attribute or download these variable lists as pdf.
