WMSTNM - plots station model data as per WMO guidelines.

       To  use WMSTNM or c_wmstnm, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in
       that order.

       #include <ncarg/gks.h>

       void c_wmstnm(float x, float y, char *imdat)

       X           (Real,  Input)  -  An X coordinate (specified in world coordinates) of a point that specifies
                   the position of the base of the wind barb shaft in the station model display.

       Y           (Real, Input) - A Y coordinate (specified in world coordinates) of a point that specifies the
                   position of the base of the wind barb shaft in the station model display.

       IMDAT       (Character, Input) - A CHARACTER*5  array  of  dimension  10  encoded  as  per  the  WMO/NOAA
                   guidelines.

       CALL WMSTNM (X, Y, IMDAT)

       Set  the  values  for  the appropriate internal parameters before calling WMSTNM to produce station model
       data plots.  The internal parameters that control the appearance of the station  model  data  plots  are:
       WBC  and  WBL.   The  appearance  of  the  wind  barb part of the station model data is controlled by the
       internal parameters applying to wind barbs.  See the documentation for WMBARB for a description  of  wind
       barbs.
