Global and Hemispheric Annual Temperature Variations Between 1854 and 1991, CDIAC NDP-022/R2Entry ID: CDIAC_NDP22
Abstract: Global and hemispheric annual temperature variations are presented for
1854-1991 based on both land and marine data. Land data are based on
meteorological data and fixed-position weather ship data and have been
corrected for non-climatic errors such as station shifts or instrument
changes. The marine data used are those in the COADS (Comprehensive
Ocean Atmosphere Data Set) compilation which ... extends to 1986, and data
from the Climate Analysis Center (NOAA) for 1980-1984. Both sea
surface temperatures (SST) and marine air temperatures (MAT) have been
used. Updates to 1991 were made with hemispheric sea-surface
temperature estimates produced by the U.K. Meteorological Office. For
each year, two versions of the northern/southern/global data are
included, one in which the influence of the El Nino/Southern
Oscillation (ENSO) related events is considered and another in which
it is not.
The COADS data were homogenized by correcting for non-climatic effects
and by removal of observations believed to be extreme outliers.
Homogenization was accomplished by comparison of marine and land data
in fifteen areas of overlap. MAT data were corrected using gridded
land data which were subsequently used to correct SST data.
Correction values were determined for compatibility between land and
ocean data. Once corrections were made to the marine data, these data
along with corrected land data were used to estimate global
The global and hemispheric annual variations presented here show
little trend during the nineteenth century, marked warming to 1940,
and relatively steady conditions to the mid-1970's, followed by a
rapid warming during the 1980's. The six warmest years in the global
record have occured since 1980 (1981, 1983, 1987, 1988, 1989,
1990). The year 1990 was the warmest year since comparable records
began in the middle of the 19th century.
All CDIAC numerical data packages include copies of pertinent
literature discussing the data, summaries discussing the background,
source and scope of the data, as well as applications limitations and
restrictions of the data.

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.
The Jones temperature anomaly data are also available as global
