Re: wrf_user_getvar question

Hello

[1] Please send all WRF questions to wrfhelp@ucar.edu
     They wrote the wrf_* functions

[2] Users can look at the NCL level functions.

%> less $NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl

Search for "wrf_user_getvar" and look at the code. You will see:

   if( any( variable .eq. (/"th","theta"/) ) ) then
        ; Potentail Temperature is model output T + 300K
        if ( time .eq. -1 ) then
          if(ISFILE) then
            var = nc_file->T
          else
            var = file_handle[:]->T
          end if
        else
          if(ISFILE) then
            var = nc_file->T(time_in,:,:,:)
          else
            var = file_handle[:]->T(time_in,:,:,:)
          end if
        end if
        var = var + 300.
        var@description = "Potential Temperature (theta) "
        return(var)
   end if
