Re: warning with open grib data

NCL is unpacking the data correctly. However, NCL's builtin
GRIB tables do not yet have entries for parameter_number 131
in parameter_table_version=130 created at the
Environmental Modeling Center.

       float VAR_131_GDS0_SFC_ave1h ( g0_lat_0, g0_lon_1 )
          sub_center : Environmental Modeling Center
          long_name : Unknown Variable Name
          units : unknown
          _FillValue : 1e+20
          level_indicator : 1
          gds_grid_type : 0
          parameter_table_version : 130
          parameter_number : 131
          forecast_time : 0
          forecast_time_units : hours
          initial_time : 01/01/2008 (00:00)

So if you have that information, you could do something like

       x = f->VAR_131_GDS0_SFC_ave1h
       x@long_name = "..."
       x@units = "..."
