GISST definition

GISST2.2 or Global Sea Ice and Sea Surface Temperature dataset (GISST) version 2.2 is in two parts:

GISST describes data which are derived from MOHSST6 and Walsh Sea_Ice Concentration data. Sophisticated statistical methods are used to produce a global coverage of monthly 1° area sea surface temperatures and sea-ice coverage (see Rayner, N.A. et al, 1996).

Ice concentrations are in tenths and the period of the data is January 1903 to December 1994. Each HDF file consists of 2 years of monthly data.

Please refer to Gisst Data set names and Content for details of the data files available on the CD-ROM (HDF version).
