Global Surface Air Temperature Variations: 1851-1984, CDIAC NDP-003/R1
Entry ID: CDIAC_NDP3_R1


Summary
Abstract: This package contains Northern and Southern mean monthly temperature variations
for 1851-1984 and 1858-1984, respectively, compiled by the Climatic Research
Unit at the University of East Anglia, United Kingdom. Each data file contains
three variables; year, monthly anomalies in degrees Celsius, and the annual
anomaly in degrees Celsius. These air temperature variations are based on
land-based meteorological station and fixed-position weather ship data
interpolated onto a 5 X 10 degree latitude/longitude grid. Station data have
been analyzed to assess their homogeneity and only reliable or corrected
station data have been used in calculating area averages. Long-term
chronologies of temperature anomalies such as these provide an important source
for checking the predictions of theories linking increased carbon dioxide
concentrations to climate changes and global warming trends.

The annual mean Northern Hemisphere temperature series shows a slight cooling
between the late 1870s and the late 1880s. The decades of the 1880s and 1890s
are the coldest of the entire record. Rapid warming occurred around 1920,
culminating in the warmest trend in the late 1930s. The annual mean Southern
Hemisphere temperature series shows fairly steady warming since the last
century, except for the interval between the late 1930s and the mid 1970s.
