Each Physical Parameter record defines a MIP variable name, associated with a CF Standard Name. Formerly known as MIP Variables in CMIP6
| Attribute | Value |
|---|---|
| cf_standard_name | gross_primary_productivity_of_biomass_expressed_as_13C |
| description | The rate of synthesis of carbon-13 in biomass from inorganic precursors by autotrophs ("producers") expressed as the mass of carbon which it contains. For example, photosynthesis in plants or phytoplankton. The producers also respire some of this biomass and the difference is referred to as the net primary production. |
