* Outline *

The directory contains analyzed ocean subsurface temperatures and
corresponding analysis errors on a 1 deg. x 1 deg. global grid at 14
levels upper 500m depth for years from 1950 to 1998. Please refer to
a document, [ 00REF_en.pdf ]:

        "Historical Ocean Subsurface Temperature Analysis 
                  with Error Estimates"

             by M. Ishii, M. Kimoto, and M. Kachi

               (Mon. Wea. Rev., 131, 51-73)

for details of the objective analysis.

The data are stored in GRIB-formatted yearly files [ temp.YYYY.grb ]
(YYYY: 4-digit year), and these data can be easily handled with the
aid of GrADS (http://grads.iges.org/grads/). A GrADS data descriptor
file (or control file) [ temp.ctl ] is prepared in the directory. When
you display the GRIB data on GrADS, GrADS requires an index/map file 
[ temp.idx ]. This file is generated by a GrADS utility command
"gribmap"; for instance, 

       $ gribmap -i temp.ctl

under UNIX. Please also remark that GRIB data are endian free.
