Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

Thank you everyone for getting back to me. My apologies for not including the location of my data. I downloaded it from http://nomads.ncdc.noaa.gov/data/rucanl/ for the appropriate date and time. Let me respond to everyone's suggestions. 1. When I run: od -c ruc2anl_130_20090605_2200_000.grb | less I get output: 0000000 051107 041111 075003 000752 000000 001034 064407 100202 0000020 062007 164003 003011 013005 000400 000000 000001 000000 0000040 000025 000400 000000 000052 001777 141401 050401 037400 0000060 100631 135354 100410 014163 032000 000351 164464 040000, etc. 2. When I run: wgrib ruc2anl_130_20090605_2200_000.grb I get output: 1:0:d=09060522:HGT:kpds5=7:kpds6=100:kpds7=1000:TR=1:P1=0:P2=0:TimeU=1:1000 mb:anl:NAve=0 3. When I run: wgrib -v ruc2anl_130_20090605_2200_000.grb I get similar output: 1:0:D=2009060522:HGT:1000 mb:kpds=7,100,1000:anl:winds in grid direction:"Geopotential height [gpm] 4. George, you mentioned that "It is possible that the program does not know about GRIB2 fields, specific to the office that created the file." By program, are you referring to the program I am using to process these data? Or are you referring to another program? I am not able to test the wgrib2 command at the moment because I do not have the permissions to install it (my advisor will have to do that). It appears that wgrib at least recognizes the *.grb file. Are the lists of the grids as they should be? Perhaps something small is getting lost in the conversion process that my processing code (using Warning Decision Support System - Integrated Information algorithms) cannot reconcile?
