Monthly Global Temperature Anomalies Year 2011

The dot maps, below, are a product of a merged land surface and sea surface temperature anomaly analysis. Temperature anomalies with respect to the 1971-2000 mean for land and ocean are analyzed separately and then merged to form the global analysis.  Note that BLUE is BELOW normal and RED is ABOVE normal, and the size of the dot is proportional to the magnitude of the anomaly.  Temperature anomalies are noted in degrees Centigrade.  The maps and data analysis are from the National Climatic Data Center. This page was produced within the Applied Climate Science Group of the School of Natural Resources, UNL.

The global data set has 132 years of data (1880-2011).
