Each red dot in the plot represents the location of at least one observation value.
Next display the output PostScript file that used a different grid by running the following command:
The plot_point_obs is useful in determining how many observation points actually fall within your verification domain.
The -gc and -msg_typ options may be used to further refine the observations to be plotted.
For example, -gc 11 -msg_typ ADPSFC plots surface observations of temperature (GRIB code 11).
