We analyze surface air temperature data from available meteorological stations with principal focus on the period 1880–1985. The temperature changes at mid- and high latitude stations separated by less than 1000 km are shown to be highly correlated; at low latitudes the correlation falls off more rapidly with distance for nearby stations. We combine the station data in a way which is designed to provide accurate long-term variations. Error estimates are based in part on studies of how… 

Tropospheric temperature trends in the Arctic: 1958–1986

Arctic temperature trends in four tropospheric layers during the period 1958–1986 are examined through analysis of a comprehensive archive of Arctic upper air meteorological data. The goals of the

Simulation of 20th century temperature trends

Results are reported from simulations with an atmospheric general circulation model (GCM) covering the 20th century. These results focus primarily on the continental surface air temperature (SAT)

High northern latitude surface air temperature: comparison of existing data and creation of a new gridded data set 1900-2000

Detection, attribution and understanding of temperature changes in the high northern latitudes depend on constraining uncertainties and resolving apparent discrepancies in observational data sets.We

Possible factors controlling global marine temperature variations over the past century

Data from the Global Ocean Surface Temperature Atlas (GOSTA), which includes 60 million ship reports for the 1856–1988 period, have been used to study global night marine air temperature (MAT) and

An analysis of global surface temperature data is described. The data originates from the European Centre for Medium Range Weather Forecasting, and covers the period 1986–1991 with a spatial

Surface air temperature and its changes over the past 150 years

We review the surface air temperature record of the past 150 years, considering the homogeneity of the basic data and the standard errors of estimation of the average hemispheric and global

Climatic warming in north america: analysis of borehole temperatures.

The magnitude of warming in the east estimated from changes in GST significantly exceeds that estimated from SAT, and a cause and effect relationship between anthropogenic activities and climatic warming cannot be demonstrated unambiguously at the present time.

Hemispheric and Large-Scale Surface Air Temperature Variations: An Extensive Revision and an Update to 2001.

This study is an extensive revision of the Climatic Research Unit (CRU) land station temperature database that is used to produce a gridbox dataset of 58 latitude 3 58 longitude temperature

Ground-air temperature tracking and multi-year cycles in the subsurface temperature time series at geothermal climate-change observatory

Long-term observations of air, near-surface (soil) and ground temperatures, collected between 1994 and 2011, monitored in the Geothermal Climate Change Observatory at Spořilov, Prague (GCCO) are

Recent changes of the tropical water and energy budget and of midlatitude circulations

Rising atmospheric H2O content and temperature above the tropical Pacific (Hense et al. 1988) stimulated research on tropical ocean-atmosphere fluxes in the belt 10° S-14° N, based on COADS data for



Northern Hemisphere Surface Air Temperature Variations: 1851–1984

Abstract A new compilation of monthly mean surface air temperature for the Northern Hemisphere for 1851–1984 is presented based on land-based meteorological station data and fixed-position weather

Variations in Surface Air Temperatures: Part 1. Northern Hemisphere, 1881–1980

Abstract We have produced, using objective techniques, a long-term series of average Northern Hemisphere temperatures based on monthly mean station data gridded on a 5° latitude by 10° longitude
