GDLIST lists data from a scalar grid. INPUT PARAMETERS GDATTIM *Grid date/time GLEVEL *Grid level GVCORD *Grid vertical coordinate GFUNC *Grid function GDFILE *Grid file GAREA *Graphics area PROJ *Map projection/angles/margins SCALE *Scaling factor OUTPUT *Output device/filename PROGRAM DESCRIPTION GDLIST lists a diagnostic grid computed from the grids in a GEMPAK grid file. The data may be listed over a subgrid. The variables GAREA and PROJ specify the data subset area. This area is only approximate; the subgrid selected will cover the subset area. GAREA must be specified as a geographic area, as an area centered on a station, as latitude/longitude bounds or as DSET or GRID. If DSET or GRID is chosen, the entire grid will be printed. Output to the terminal or to a file will be 80 columns wide. If the output is sent to a file, the file will be named gdlist.fil if no name is specified. EXAMPLES 1. List surface temperature from the April 5 00Z NGM cycle for the 0-h forecast time. The output will be to the terminal. The data subset area is a zoomed area centered on Colorado. GDATTIM = 0405/00f00 GLEVEL = 0 GVCORD = pres GFUNC = tmpf GDFILE = ngm.grd GAREA = co** PROJ = mer SCALE = OUTPUT = t 2. Compute the divergence and list the output over the US. Scale the data by 10**5 and write the output to a file called div.us. GFUNC = div (wnd) GAREA = us PROJ = ced SCALE = 5 OUTPUT = f/div.us ERROR MESSAGES [GDLIST -1] Fatal error initializing TAE.
