Dear Ravan,

I also tried to drive WRF-V3 with ECMWF forecasts on model levels.
I ran WPS using Vtable-ECMWF.sigma, then calc_ecmwf_p.exe to create the PRES 
fields.
But at the WRF stage, em_real failed at the very beginning, during a vertical 
interpolation, and my conclusion, after digging into the code, was that 
em_real required the geopotential on all levels.
But Z is only available at the surface level at MARS in forecast data sets, 
not on the upper air hybrid levels.
I am curious to know how you do with ECMWF hybrid levels.
Do you run WFR-2.2.1 or WRF-V3 ? Are there, apart the Vtable and 
calc_ecmwf_p.exe, other tricks to configure or use ? What did I miss ?

Thanks
