[ncl-talk] Regridding WRF corvilinear grid to gpm rain rectlinear grid

[Barry Lynn]

Dear Ronald:

I have used regrid to regrid to both the original WRF grid and a more
sparse grid.  However, its main task is to regrid to the original grid in
rectilinear coordinates (unless you tell it otherwise).

You can interpolate from a fine grid to a coarse grid using the programs
available (e.g., area_hi2lores_Wrap).

Please see lines 320,386 in the program attached (that calculates
frontogenesis).  In this program, I used a more sparse version of the WRF
grid as the destination grid. If you are going to use a grid from a
different data set, then it would be best if the new grid will be smaller
than the WRF grid (so you don't interpolate zeros).
