first i suggest that you subsample your global data in the
area of the region you are interested in since data outside
of this area would not be used in an interpolation.
since you have regional data, you can not use any of the
spherical harmonic based interpolation routines. That
leave natgrid which does natural neighbor interpolation,
dsgrid which does inverse distance weighted averaging,
and linint2 which uses bilinear interpolation.
an example of the latter and a link to other regridders is at:

there is an example of outputting netCDF as well as other
NCL IO topics at:
