Dear cf-metadata,

 I propose additional standard names.
To separate them from my previous proposals I continue the numbering from 
my last emails.

24. snow_density; kg m-3
25. surface_net_downward_radiative_flux_where_land; kg m-3
26. volume_fraction_of_frozen_water_in_soil; 1
27. liquid_water_content_of_snow_layer; kg m-2

open answers from 10.Apr.2006-email
 downward_heat_flux_at_ground_level_in_snow (already in list) is OK 
instead of snow_basal_heat_flux

The momentum fluxes as well as the other vertical fluxes are positive 
when downwards in ECMWF convention.
