The United Kingdom Meterology Office (UKMO) Hadley Centre for Climate Research Global Sea Ice Coverage and Sea Surface Temperature dataset for the period 1870-present. Containing a combination of monthly globally complete fields of SST and sea ice concentration on a 1°x1° latitude-longitude grid from 1871 based upon a reanalysis of in situ sea surface observations and satellite derived estimates at the sea surface. The CSIRO version of this dataset has had all years concatenated to form one file and has been processed to calculate the following datasets: 1870-2006: Monthly & Monthly no-ice, Monthly Anomaly & Monthly Anomaly no-ice , Climatology & Climatology no-ice, Seasonal Anomaly & Seasonal Anomaly no-ice. 1870-2007: Monthly & Monthly no-ice, Monthly Anomaly no-ice, Climatology no-ice, Seasonal Anomaly no-ice. 1979-2005: Monthly, Monthly Anomaly, Climatology. 1980-1999: Monthly no-ice, Seasonal no-ice, Climatology no-ice.
