Hi:
I am doing a simulation over complex and sharp terrain with WPS and WRF 4.2 and FNL ds083.3 forcing data (isobaric levels). The run crashed at startup so I went back to the preprocessing and discovered that at least in some regions levels 2 to 8 (over 34) are below level 1 (ground) in the met_em files. However, I did not detect anything suspicious in wrfinput. I was told to use only 4 pt interpolators in METGRID.TBL to avoid the crossing of the lowest levels but it did not work for me. So my questions are: Can real.exe overcome the problem of having 7 or less levels below the surface in some regions ? Or can I somehow fix the crossing of levels ? What tests should I perform on wrfinput to ensure its integrity ? I would very much appreciate your suggestions.
