This data set contains estimates of global and hemispheric annual temperature variations,
relative to a 1950 through 1979 reference period, for 1861 through 1991. The estimates
are based on corrected land and ocean data. Land data were derived from meteorological
data and fixed-position weather-ship data that were corrected for nonclimatic errors,
such as station shifts and/or instrument changes. The marine data used were those in the
Comprehensive Ocean-Atmosphere Data Set (COADS) compilation, which with updates covers
to 1986. Updates to 1991 were made with hemispheric sea-surface temperature estimates
produced by the U.K. Meteorological Office. Each record includes year and six annual
temperature variations: one estimate each for the globe, the Northern Hemisphere,
and the Southern Hemisphere and another estimate each that reflects an adjustment to
account for the influence of El Niño/Southern Oscillation events. The data are
in one file of 13 kB.
PLEASE NOTE.
Updates to these global and hemispheric temperature
anomaly series produced by Jones et al. are available through CDIAC's
Trends Online. NDP-022 contains data only through 1991, so users
are encouraged to access the most recent data through Trends Online.
