Use of WRF with GEFS data

Hi,

I'm trying to use WRF model with GEFS data downloaded from ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/gens/prod/ using Vtable.GFSENS. When I execute ./metgrid.exe it says:
ERROR: The mandatory field TT was not found in any input data. How can this error be solved?

Julio.

Hi,
Looking at your ungrib.log, it doesn't look like the ungrib program is actually finding any data for most of the variables. Your ungrib log shows lines like

I would recommend using the util/g1print.exe (or g2print.exe) program to take a look at your raw input data and check that you have the necessary variables and that the codes match those shown in the Vtable you're using.

I'm not sure. I'm not very familiar with GEGS data, and we aren't the authors of that file.
