Grid Issues

HELP!
I'm not sure what to think about this but, it does seem to be an issue to me.
Jeff, I think the problem I was having with grib2 files were related to the ftp program I use because I was able to get them to covert correctly this morning in NGRB2PCG32 without any problems when I used the grib download part of WINGRIDDS. However, I have run into a problem with the Grid #003, 1x1 degree lat/lon grid.
Data does not display correctly.
Should look like the Grid #004, 0.5x0.5 degree lat/lon grid
So, I ran the ALAT and ALON commands for the 003 grid. Everthing looked fine with the lats but the lons
So, next I thought I'd run the ALAT and ALON commands for the 004 grid to see if they were ok. Again, lats are fime but, the lons are not.
Should not the lons in the griddata file line up with that drawnn on the map? My biggest issue with all this is that the data in the 003 grib files is not displaying like the 004 grib files. But, I'm also concerned about the lons not displaying correctly.
Data source: ftpprd.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gfs.t00z.pgrbf03.grib2
for the Grid #003, 1x1 degree lat/lon grid.
The Grid #004, 0.5x0.5 degree lat/lon grid is already in the grib download menu.
Thank you,
Kevin
