Dear All,
I would like to propose the following list of variable names to be
included in the list of CF standard names. They are input/output
variables for the COSP (CFMIP Observational simulator Package). Many of
them are requested by CFMIP-2, as part of CFMIP5.
Please let me know your comments.
Best wishes,
Alejandro
------------------------ List of variables --------------------------
These are the input variables.
