May 03 1996:  Procedure for creating STR-sst.T42.0596,
	       the Climatological SST dataset, 12 months, global 
	       coverage

   Cray disk file:
	   	 /ccm/CCM3/data/STR-sst.T42.0596
   Mass Store tape:
	   	 /CCM3/data/STR-sst.T42.0596

   Alias:    STR-sst.0895

 Variables:  SST (Sea Surface Temperature) 
 Units:      Celcius  
 Coverage:   Global.  
 Dates:      12 files each a monthly average from JAN to DEC.
             Dates are valid near the "middle" of the month as indicated
             by the dates in the integer header
 Format:     CCM2 History tape format (see NCAR TN-379+IA 'Users's Guide to NCAR CCM2').

 MSS Name:   /MVERTENS/T42SST_SPLINE.CCM2_MV
 History:    The source of the above data is the Shea, Ternberth, Reynolds
             2x2 degree sst climatology. The source file is contained within 
             NCAR's DSS ds289.0  

             Dennis Shea used a two-dimensional cubic spline was to interpolate 
             the 2x2 grid to a T42 grid. Ice values were set to -1.8C. 

             Doug Lindholm (CAS) put the interpolated file into
             history tape format. He also changed the units to degrees Kelvin.
             
             Mariana Vertenstein then adjusted the date to a mid-month value.
