[Wrf-users] interpolating to height above ground

As far as I know, there are some good programs such as RIP4 that allows
you to vertically interpolate WRF data, however most of them (including
RIP4) use linear interpolations.
Matlab is a good option, it can read netCFD files and you it can be
easily programed to fit different interpolating functions depending on
the meteorological parameter you want to determine. For instance, for
the wind speed interpolation, the best functional relation is the
similarity theory, in order to be consistent with the boundary layer
physics of the WRF , although is easier and faster to fit either the
power law or the neutral logarithmic profile for the wind vertical
