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
