How to directly get atmosphere variables at specific pressure level?

[jie_wong]

Hello,
I notice that I can output these variables at specific pressure level directly by set fincl1='U200','V200','U850','V850','OMEGA500','OMEGA850'. But it seems UV at other level (like 700,500hPa) can not be gotten in that way. I konw it can be gotten output the whole level of U or V or other variables(such as RH, PHIS), but then the files would be very large.
So I want to ask how to directly get atmosphere variables (U,V,relative humidity, PHIS. etc. ) at specific pressure level?

Thanks,
Jie

The variables from the model output are all on hybrid sigma-pressure levels. You need to interpolate them onto the standard pressure levels.
