This dataset contains data tables of Global, Hemispheric, and Zonal Temperature Anomalies. Anomalies are relative to the 1951-1980 base period means. Data from NASA Goddard Institute for Space Studies. The NASA GISS Surface Temperature (GISTEMP) analysis provides a measure of the changing global surface temperature with monthly resolution for the period since 1880, when a reasonably global distribution of meteorological stations was established.
