Analysis uncertainty occurs because of data errors and incomplete sampling over the historical period. This manuscript documents recent improvements in NOAA’s merged global surface temperature anomaly analysis, monthly, in spatial 5° grid boxes. These improvements allow better analysis of temperatures throughout the record, with the greatest improvements in the late nineteenth century and since 1985. Improvements in the late nineteenth century are due to improved tuning of the analysis methods. Beginning in 1985, improvements are due to the inclusion of bias-adjusted satellite data. The old analysis (version 2) was documented in 2005, and this improved analysis is called version 3. STUDY NOTES: The MLOST anomalies are computed relative to a 1971-2000 baseline, following the World Meteorological Organization convention. The current v3b ERSST analysis uses only in situ SST data, but other than the exclusion of satellite SST data v3 and v3b processing are the same.
