[gembud] merging awip32-fixed.gem with a NARR sub-region

List:

I've downloaded a small sub-region of NARR data from NOMADS covering just a
portion of the NE CONUS and have converted the files to *.gem.

I'm trying to add the awip32-fixed.gem file with these subdomain NARR
files, but the spatial domains don't match, obviously. I have no trouble
adding this grid file for the entire NARR domain.

I thought it would be easy to "crop" the awip32-fixed.gem file to the same
lat/lon boundaries as my NARR data, and go from there, but I'm having
difficulty with this. Anyone have any ideas? Is there a better way?

The raw metadata for the two files from GDINFO is listed below...

Thanks in advance for any assistance you can provide.
