Global Time Series

Please note, global and hemispheric temperature anomalies are with respect to the 1901-2000 average. Coordinate temperature anomalies are with respect to the 1991-2020 average. All other regional temperature anomalies are with respect to the 1910-2000 average. Monthly precipitation data are not available until a few days after temperature data are released.
