[Wrf-users] ETA to Pressure level calculation?

[Nikhil Garg]

the eta might or might not correspond exactly to your desired pressure
levels, if you want to get the data, you have to use "ncl" or "wrf_interp".

for ncl, you should check out ncl website, where you can interpolate 3d
data from wrf to specified pressure levels, while for wrf_interp, you have
to download it from wrf user website, and compile it.
