Dataset
Summary
This dataset includes local mean surface temperature anomalies for each month from 1850 to 2024 and for each 5° latitude by 5° longitude grid cell of the Earth. The impact of sea ice concentrations on surface temperature anomalies is also available. Estimated temperature anomalies include the impacts of sea ice concentrations and an internal variability pattern. The internal variability pattern corresponds well to the El Niño Southern Oscillation. Results of sensitivity tests using alternate sea ice source datasets from the Japanese Meteorological Agency (COBE-SST3) and the National Snow and Ice Data Center (modified G10010v2 appended with G02202v4) are also available.

The maximum likelihood estimation approach allows for the estimated field of surface temperature anomalies to be temporally and spatially complete for the entire time period and for the entire surface of the Earth. Other estimates of this dataset are also spatially and temporally complete.

Description
The quality of this dataset has been approved by Bruce T. T. Calvert on January 31, 2024. This dataset is a further derived product (classifying as a level 4 data processing level) derived from various source datasets, including land surface air temperature anomalies of HadCRUT5, exposure bias adjustments of Wallis et al. (2024), sea surface temperature anomalies of HadSST4, sea ice coverage of HadISST2, land mask data of OSTIAv2, the surface temperature climatology of Jones et al. (1999), the sea surface temperature climatology of HadSST3, surface elevation data of GMTED2010, and climate model output of CCSM4 for a pre-industrial control simulation. Sensitivity tests of HadCRU_MLE_v1.3 use alternate sea ice source datasets (COBE-SST3, G10010v2, and G02202v4). These source datasets either have had extensive quality control or are themselves further derived products based on source datasets that have had extensive quality control.
Description
Due to the maximum likelihood estimation approach used, the estimated field of surface temperature anomalies is temporally and spatially complete for the entire instrumental period and for the entire surface of the Earth. Other estimates of this dataset are also spatially and temporally complete. As a result, there are no missing values in the dataset.
