[Wrf-users] Mismatch between Metgrid_soil_levels and the recently upgraded GFS

Dear Elena Maria,

with the new gfs files you have to change grib2 codes in Vtable.GFS in
order to get TSOIL in the input. Seems that ./real.exe does not take any
soil level into account if TSOIL is not present. If you revise the output
on the screen while running ungrib, you probably see some 0's in the upper
lines below the TSOIL variable.
The problem was solved for me changing the Vtable.GFS by the lines

   11 | 112  |   0  |  10  | ST000010 | K       | T 0-10 cm below ground
layer (Upper)    |  2  |  0  |  2  | 106 |
   11 | 112  |  10  |  40  | ST010040 | K       | T 10-40 cm below ground
layer (Upper)   |  2  |  0  |  2  | 106 |
   11 | 112  |  40  | 100  | ST040100 | K       | T 40-100 cm below ground
layer (Upper)  |  2  |  0  |  2  | 106 |
   11 | 112  | 100  | 200  | ST100200 | K       | T 100-200 cm below ground
layer (Bottom)|  2  |  0  |  2  | 106 |
   11 | 112  |  10  | 200  | ST010200 | K       | T 10-200 cm below ground
layer (Bottom) |  2  |  0  |  2  | 106 |

The changes are in the "Discp" and "Param" columns. Hope this will also
solve your problem.

cordial saludo,

Thorsten
