To: ncl-talk at ucar.edu


Dear NCL talk,

I am running into an issue with regridding from the GFS global grid, which
are grib files, to the regional WRF grid that I specify for my WRF runs.
When I do a test script to see what the regridded dataset looks like, it
does not match up with the GFS fields. Right now I am just looking at MSLP.
I am using the ncl function rgrid2rcm. Is this not the correct regrid tool
for my applications? I am not sure what I am doing wrong, if anything.
There are no error messages when I run the script. I have uploaded a grib
file and the wrfout file to the ftp site. The postscript files of the WRF
output (correct grid) and my interpolated grid from GFS to WRF is attached,
along with a script I am using. Any help would be most appreciated.

Thanks,
