[ncl-talk] Regridding GFS rectilinear grid to Polar Stereographic regional grid

[Andrew Kren - NOAA Affiliate]

Dear ncl-talk,

I have a code where I want to do a a difference in precipitation between
the observed precipitation and model output from the GFS model. In order to
compute the difference I regrid the data using rgrid2rcm_Wrap. The observed
precipitation is on a polar stereographic 2d lat/lon grid. When I did the
regridding, I am getting missing values at all locations. Is this not the
best way to regrid the data?

The issue is that the observed data is on either a CONUS grid, or an Alaska
grid, but both are grib files with a defined grid. Should I use ESMF. I
attached the code and the 'exit' statement is where I stopped to try to
print out the values after computing the difference of gfs precip minus
observed precip. I am not sure the best way to go about doing this
comparison.

Thanks,
