Re: lat/lon error and missing file error

The high-level graphical interfaces [eg: gsn_csm*] query the
variable to be plotted. When performing (say) contours
over a map, the interfaces MUST know the latitude
and longitudes of the variables.

eg: x(lat,lon)

         where lat and lon are (say) 1D coordinate variables.
         These coordinates are required to have COARDS
         conforming units "degrees_north", "degrees_east"

So assign units to the lat/lon arrays

        lat_at_units = "degrees_north"
        lon_at_units = "degrees_east"
