GLOBAL FORECAST SYSTEM
ss2gg converts a sigma file to a grads binary file and creates a corresponding descriptor (ctl) file

A version of ss2gg is available at:
   /climate/save/wx24ds/glopara/util/ss2gg   (on mist and dew)
   /mtb/save/wx24ds/glopara/util/ss2gg       (on haze)
though more recent versions may exist.


Original Author: Mark Iredell


Usage: ss2gg sigfile(s) gggfile ctlfile idrt imax jmax

where:

sigfile(s) = sigma file(s) to be converted to 
     grads readable ieee files

gggfile = output file name

ctlfile	= name of grads descriptor file (output)

idrt = output grid type 
         0 = linear S->N 
         4 = gaussian 
       256 = linear N->S

imax = integer number of longitude points for output grid

jmax = integer number of latitude points for output grid

!                (IDRT=4 FOR GAUSSIAN GRID,
!                 IDRT=0 FOR EQUALLY-SPACED GRID INCLUDING POLES.
!     imax     - Integer even number of longitudes for output grid
!     jmax     - Integer number of latitudes for output grid
