NOTE: The GISST time series will be discontinued on February 2003. HadISST , also from the Hadley Centre for Climate Prediction and Research, is a superior product. We recommend the usage of HadISST over GISST.

Monthly longterm global SST and sea ice analysis. In situ sea surface observations and satellite derived estimates at the sea surface are included in the analysis. SST bucket corrections have been applied to gridded fields from 1871 through 1941. And a blend of satellite AVHRR (for SST), SSMI (for ice), and observations are used in the modern periods.

Access to GISST 2.3b has proprietary restrictions. Users must register with the authors before receiving the data. This is easy to do. Simply print a copy of the registration form restr_form) and follow the FAX instructions. When this is completed contact Steve Worley (NCAR) worley@ucar.edu and the data will be made available.
