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.
GEMPAK-GDLIST>r
GDLIST PARAMETERS:
Grid file: eta212
GRID IDENTIFIER:
TIME1 TIME2 LEVL1 LEVL2 VCORD PARM
050712/1200F000 0 NONE SWRD
GAREA: uslcc
SCALE FACTOR : 10** 0
OUTPUT: TERM/
MINIMUM AND MAXIMUM VALUES 0.00 581.75
Enter <cr> to accept parameters or type EXIT:
Grid file: eta212
GRID IDENTIFIER:
TIME1 TIME2 LEVL1 LEVL2 VCORD PARM
050712/1200F000 0 NONE SWRD
AREA: uslcc GRID SIZE: 185 129
COLUMNS: 28 169 ROWS: 12 106
