Dear wrf user,

Hope every one is doing great! I need your help running wrf with Noah Land
Surface Scheme (sf_surface_physics  =2). With other pressure level data and
surface data I put soil temperature data and surface roughness data from
ERA interim daily data set. could you please tell me what input data sets
are required to use Noah scheme? I did not change any table or any thing
except namelist. input. The real.exe showing a message "Could not find
level above ground".  Please see the attached namelist.input file.

Thanking in anticipation.
