Hi Nick,
     You can use the ARWpost module to convert the orginal model levels into
pressure levels.  I assume you have all the other knowledge for using the
ARWpost utility. If you do not, please refer to the WRF user guide.  Then
what you need to do is to modify the namelist.ARWpost to set the
interp_method=1 (for user specified pressure/height) and the
interp_levels=1000, 975,950...or any setting of the vertical pressure levels
which ARWpost utility will interpolated the model data into your setting
levels.
Hope this helps.
