If you have a file with existing navigation parameters use GDMOD to move your desired data into that spatial domain: Ref: https://www.unidata.ucar.edu/cgi-bin/gempak/manual/programs_index?gdmod If you need to create specific navigation parameters to suit your needs, use GDCFIL to create from scratch, or 'copy' using CPYFIL: Ref: https://www.unidata.ucar.edu/cgi-bin/gempak/manual/programs_index?gdcfil Cheers, --patrick -------------------- Patrick L. Francis VP Media Logic Group http://www.medialogicgroup.com http://www.hamweather.com http://www.alertsbroadcaster.com http://www.modelweather.com FB: http://www.facebook.com/wxprofessor -- From: gembud-bounces@xxxxxxxxxxxxxxxx [mailto:gembud-bounces@xxxxxxxxxxxxxxxx] On Behalf Of Peter Banacos - NWS Federal Sent: Wednesday, February 06, 2013 11:55 AM To: gembud@xxxxxxxxxxxxxxxx Subject: [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.
