Gridded Monthly Data of Maximum Likelihood Estimates of Temperatures using Data from the Hadley Centre and the Climate Research Unit (Version 1.4)

Calvert, Bruce

Dataset
Summary
This dataset includes local mean surface temperature anomalies for each month from 1850 to 2025 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 G02202v6) 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.
