[Wrf-users] surface fields

[Agnes Mika]

Dear WRF users,

 I need the surface (first model level, eta=1) values of the following
 variables: temperature (or potential temperature, doesn't matter) and
 water vapour content (mixing ratio or any other water vapour variable
 is fine). 

 I saw in the WRF output that the only 3D variables which have their
 values on the first model level also present in the file are the
 geopotential (PH and PHB) and the vertical velocity (W). All the
 other 3D variables start one level above the surface.

 As for the temperature, I found two variables which might be usable:
 sea surface temperature (SST) and surface skin temperature
 (TSK). Could you please tell me the meaning of these variables? I was
 expecting them to be identical (temperature of the upper few mm
 layer) but they are (virtually) the same only above water and there
 are significant differences above land (up to about 5 K).

 As for the water vapour content, I couldn't find anything (though
 this is crucial for the study I am working on). Is there something I
 could use (some manipulation of the top layer soil moisture?) or do
 I need to be content with the 2m values?

Thank you for your help.

Regards,
Agnes
