The programs ss2gg and ss2grb show how a modern GFS sigma (actually
a spectral hybrid sigma-pressure) file can be read using the sigio
library.  

   ss2gg :  spectral sigma to Gaussian grid
               output is hybrid level data on a Gaussian or lat-lon grid

   ss2grb : spectral sigma to grib2
               output is grib2 data on a lat-lon grid
               data is on the hybrid level and pressure level
               underground pressure levels are set to undefined.

Comments: ss2grb is a simple postprocessor.  The pressure level data
has been compared to the NCEP post and main differences is that ss2grb
does not limit RH to values between 0 and 100 and the treatment of
underground values.
