[gradsusr] netcdf to grib

[Jeff Duda]

I'm quite accustomed to viewing WRF output in Grads.  I used ARWpost as
well.  It worked for my system, so I didn't have to worry about opening
most netCDF files directly.  However, I have had to open them recently.  I
had the same problem, so I wrote a full-on control file for the netCDF
file.  The page Jennifer linked contains links to instructions for writing
a descriptor file for your WRF output so you can view it in Grads.  If you
have any problems with that, I can help you.

As far as the reason the error comes with sdfopen, that remains a mystery
to me since lat/lon data are included in standard WRF output.
