Chirag, Your GDATTIM in gdlist should be a single time, such as f000, where it appears to be "ALL" in the list below. Also note that your decoded file is full, with 18000 grids- so you will want to increase the maximum number of grids to 24,000 in the future (in the current $GEMTBL/grid/gribkey.tbl this is 24000). The following works for me today: % gdlist GDATTIM Grid date/time f000 GLEVEL Grid level 0 GVCORD Grid vertical coordinate none GFUNC Scalar grid swrd GDFILE Grid file eta212 GAREA Graphics area uslcc PROJ Map projection/angles/margins|dr lcc SCALE Scalar scale / vector scale 0 OUTPUT Output device/filename t Parameters requested: GDATTIM,GLEVEL,GVCORD,GFUNC,GDFILE,GAREA,PROJ,SCALE, OUTPUT.
