[Met_help] PB2NC config file

[Ruifang Li]

John,
I get this error when I run point_stat tool:

*** Running POINT_STAT on WRF OUTPUT ***
***          UGRD                ***
GSL_RNG_TYPE=mt19937

----------------------------------------

Reading records for UGRD/P1000.
For UGRD/P1000 found 1 forecast levels and 0 climatology levels.


ERROR: is_grid_relative() -> Unsupported grid type value: ^A


But point_stat works well with TMP. I looked at code read_grib.cc and found
out

// FUTURE WORK: ADD SUPPORT FOR THE MERCATOR PROJECTION

   //
   // Mercator Projection Grid
   //

else if(r.gds->type == 1) {

      cerr << "\n\nERROR: read_gds() -> "
           << "Mercator grid type " << (int) r.gds->type
           << " not currently supported.\n\n"
           << flush;
      exit(1);
   }

My wrf forecast use Mercator projection, It looks like that I can not do U,
V, WIND using MET2.0, right?
Are there other ways that I can try?

Thanks,
Ruifang
