These are text-formated files, storing historical ocean temperatures.
The following shows a sample program for reading the data.
In the this sample program,

   dat(1,    1) contains T at 89.5S   0.5E,
   dat(360,  1) contains T at 89.5S 359.5E,
   dat(  1,180) contains T at 89.5N   0.5E, and
   dat(360,180) contains T at 89.5N 359.5E,

at k-th level. Variable "zlev" gives you depth of analyzed data.
Variable "elm" indicates which the record stores temperature or
analysis error.

      parameter (im=360,jm=180,km=24)
      dimension dat(im,jm)
      integer   idat(im)
