[ncl-talk] Problem with regrid from GFS grib files to WRF grid

[Wei Huang]

Andrew,

I will be better that you use WRF gridding tools to do the job, rather than NCL.

Subject: [ncl-talk] Problem with regrid from GFS grib files to WRF grid

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,
