[CF-metadata] OLR, soil moisture content and D20

[Francisco Doblas-Reyes]

Hi,

I would like to ask for the creation of three new standard names:

1) toa_net_downward_longwave_flux (units W m-2): Although there is no 
downward flux of longwave radiation at the top of the atmosphere, this 
name would allow to have a set of consistent names for all the fluxes in 
forecasts carried out by the European coupled models, which consider all 
the fluxes being positive downwards.

2) volumetric_soil_moisture_content or volume_fraction_of_water_in_soil 
(units m3 m-3): Some soil schemes coupled to atmospheric general 
circulation models use volumetric soil moisture content instead of mass 
or thickness units. This variable would contain the volumetric soil 
moisture integrated from the surface to the bottom of the lowest layer.

3) isotherm_depth (units m): The depth of the 20C isotherm is a useful 
variable to diagnose, among other things, the variability of the 
tropical upper oceans. However, I haven't been able to find any simple 
way to code this variable using the CF standards.

Best regards,
Paco
