20050712: 20050702: DSWRF parameter in ETA file?

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.
