[Wrf-users] interpolating to height above ground

[Craig Mattocks]

You can try this WRF utility:

http://www.mmm.ucar.edu/wrf/OnLineTutorial/Tools/p_interp.htm

It has namelist options for linear in p, linear in log(p), and underground/aloft extrapolation.

Just be aware that it is lacking robustness in some of its calculations, so you may have to set range limits in certain places to prevent overflows/underflows.
