[CF-metadata] new standard_names

[Burkhardt.Rockel at gkss.de]

Dear All,

in the EU project ENSEMBLES we intend to convert the climate simulations 
of about 10 different regional climate models into the netCDF 
CF-convention standard. 
Some of the output quantities are not in the CF standard name tables  (I 
used the search utility provided on the WEB to check this).
I produced a list of necessary standard names to be approved by the 
CF-group (see below) which also includes additional quantities often used 
in our simulations.


Beste Regards
Burkhardt
