1-6     A6     SSTMOD - Introduces the application/                             
               estimation of a sea surface topography                           
               model which employs a number of functions                        
               evaluated at several points located on                           
               a uniform grid on the globe.  The sea                            
               surface topography height at a given                             
               location is evaluated by interpolation                           
               and represents the height from the geoid                         
               to the mean sea surface.  The user may 
               input the grid file either in IIS or in
               IIE.  For large grid files IIE input is
               recommended.

11-12   I2     Number of real variables on one record of

               include all the coefficients that describe
               one function in the following order:
               constant term
               periodic terms -

NOTE [1]:  This card must be followed by a number of SSTCOF cards which         
           represent the total number of functions evaluated per grid           
           point.                                                               
                                                                                
NOTE [2]:  Files input from IIE:
           Two files (units 27 and 28) must be brought into the directory
           where GEODYN will execute.  These files which are specific to the
           machine on which they are used, represent the direct access
           function file (27) and the matching grid file (28).  See Vol. 5
           Sect. 2.10 for a description of the files
