The dataset is presented as an ensemble of 100 dataset realisations that sample the distribution of uncertainty in the global temperature record given current understanding of non-climatic factors affecting near-surface temperature observations. This ensemble approach allows characterisation of spatially and temporally correlated uncertainty structure in the gridded data, for example arising from uncertainties in methods used to account for changes in SST measurement practices, homogenisation of land station records and the potential impacts of urbanisation. The HadCRUT4 data are neither interpolated nor variance adjusted. ongoing https://psl.noaa.gov/data/gridded/images/small/hadcru4.png Long Term Mean HADCRUT4: Median Surface Air Temperature Monthly Median Anomaly from 100 ensemble members HADCRUT4: Median Surface Air Temperature Monthly Median Anomaly from 100 ensemble members HADCRUT4: Median Surface Air Temperature Monthly Median Anomaly Error from 100 ensemble members theme Variables 2013-02-05 revision eng; USA 1850-01-01 2021-11-01 Morice, C.
