Since we are moving towards to use global_chgres_driver.sh and
global_chgres.sh, there is no need to test fv3gfs_chgres.sh and
We can worry about getges.sh later.

There is no need to change the order of the records in the combined file. I
assume you attached nsst variables to the end.
As for nx-ny vs nlat-nlon, it is your call. I donot think they matter for
now. But for consistency, you can change them to nx-ny.
