[CF-metadata] proposed new ocean standard names to support CMIP6
Dear all
Stephen Griffies and I propose some new standard_names, detailed below, for
ocean models participating in CMIP6. These are quantities which have been
included in the list of diagnostics proposed by the CLIVAR Ocean Model
Development Panel. The names are in the following groups:
miscellaneous - there are four of these
X_at_sea_floor, where X is temperature or salinity. There are two varieties
of temperature, potential or conservative
integral_wrt_depth_of_product_of_sea_water_density_and_X
ocean_C_overturning_mass_streamfunction_due_to_P, where C is a vector
component and P is a model process
northward_ocean_heat_transport_due_to_P
tendency_of_sea_water_X_expressed_as_X'[_due_to_P], where X is temperature
and X' heat content, or X is salinity and X' salt content.
The proposed names are given below with units, short name of use for CMIP, and
a short description. The proposed CMIP short name is just for information -
this is not part of the CF standard. We have tried to make use of existing
patterns of CF names or extend them in natural ways. Comments welcome. Thanks.
Cheers
