CRUTEM.5.0.0.0: Climatic Research Unit (CRU) gridded near-surface air temperature anomalies over land
CRUTEM (Climatic Research Unit TEMperature) is a gridded dataset of global historical near-surface air temperature anomalies over land at a monthly timescale. It is a collaborative product of the Climatic Research Unit at the University of East Anglia, the Met Office Hadley Centre and the National Centre for Atmospheric Science. CRUTEM also contributes the land air temperature station data to the global (land and ocean) temperature dataset called HadCRUT.
CRUTEM5 is the fifth major version of the dataset, covering the time period from 1850, with a spatial resolution of 5° latitude by 5° longitude and a monthly-mean time resolution. The gridded temperature anomaly fields are based on a compilation of monthly-mean temperature observational records from weather stations. This compilation contains 10639 station records, but only 7983 records had the necessary coverage to be used for producing the gridded dataset. Anomalies are differences from average conditions in the 1961-1990 period. Hemispheric and global mean time series of land air temperature anomalies are also provided.

Daily or sub-daily measurement of near-surface air temperature at 10639 weather stations around the world.
Calculation of daily and then of monthly average temperature. Calculation of monthly averages is done by data providers.
Compilation by National Meteorological Services (NMS) of multiple stations, with quality control and in some cases homogeneity assessment and homogenisation.
Compilation by Climatic Research Unit (CRU) of data acquired from NMS and other compilations into a global station database.
Quality control and outlier identification by CRU.
Quality control and outlier identification by UK Met Office of near-real time data provided by NMS via global telecommunication systems.
Conversion to monthly temperature anomalies (relative to each station’s normal, i.e. the temporal mean over the 1961-1990 reference period) by CRU and Met Office.
Gridding of the station data onto a regular grid by CRU and Met Office.
Calculation of uncertainties from multiple sources that affect each grid-cell value by Met Office.
Calculation of global and hemispheric means, with uncertainties from multiple sources including incomplete spatial coverage, by CRU and Met Office.
