Dataset
Summary
This dataset includes global mean surface temperature anomalies for each year from 1850 to 2023. The impacts of sea ice concentrations and an internal variability pattern on surface temperature anomalies are also available. Estimated temperature anomalies include these impacts. 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-SST2) 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 global mean surface temperature anomalies to be temporally complete for the entire time period. Other estimates are also temporally complete.

Description
The quality of this dataset has been approved by Bruce T. T. Calvert on September 22, 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 temperatures of Chan, Gebbie and Huybers (2024), non-infilled DCLSAT, GHCNv4, and CRUTEM5; sea surface temperatures of DCSST; sea ice coverage of HadISST2; measurement and sampling uncertainties of CRUTEM5 and HadSST4; land mask data of OSTIAv2; surface elevation data of GMTED2010; and climate model output of CCSM4 for a pre-industrial control simulation. Sensitivity tests of DCENT_MLE_v1.0 use alternate sea ice source datasets (COBE-SST2, 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 global mean surface temperature anomalies are temporally complete for the entire time period. Other estimates of this dataset are also temporally complete. As a result, there are no missing values in the dataset.
