[Wrf-users] WRF output into regular grid

you'll need regridding software.  I use Matlab, Ferret, Python or a
custom C++ program to do this.

Matlab:     griddata()
Ferret:     scat2gridgauss_xy   or   curv2rect
Python:     matplotlib + basemap package, or custom interpolation

You have the WRF grid point center and edge coordinates available as
XLONG, XLAT, XLONG_U, XLAT_U, XLONG_V, XLAT_V.  With these you can
interpolate to any other location.

I'm sure NCL has a solution as well, but I'm not familiar with it.
Perhaps someone else can indicate how to regrid using NCL.

Kind regards,
     Hein
