Merged Land and Ocean Surface Temperature, Version 3.5 (Version Superseded)

*This version has been superseded by a newer version. It is highly recommended for users to access the current version. Users should only access this superseded version for special cases, such as reproducing studies. If necessary, this version can be accessed by contacting NCEI.* The historical Merged Land-Ocean Surface Temperature Analysis (MLOST) is derived from two independent analyses, an Extended Reconstructed Sea Surface Temperature (ERSST) analysis and a land surface temperature (LST) analysis using the Global Historical Climatology Network (GHCN) temperature database. The data is merged into a compilation for monthly global surface temperature dating back from 1880 to the present, updated monthly, in gridded and timeseries formats. The changes from prior versions include improved tuning procedures, processing sea ice bias correction directly from ERSST, and the addition of satellite data. This data set is used in climate monitoring assessments of near-surface temperatures on a global scale.
