Hadley Centre Global Sea Ice and Sea Surface Temperature (HadISST)

This dataset includes HadISST1 and HadSST2 from U.K. Hadley Centre. HadISST1 is a unique combination of monthly globally-complete fields of SST and sea ice concentration on a 1 degree latitude-longitude grid from 1870 to date, and HadSST2 is a monthly global field of SST on a 5-degree latitude-longitude grid from 1850 to date, neither interpolated nor variance adjusted. The data may also be obtained from the server at the Hadley Centre in the UK.
