Merged Land and Ocean Surface Temperature, Version 3.5

Metadata Updated: September 19, 2023

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.

Lineage The Merged Land and Ocean Surface Temperature Analysis (MLOST) combines a global sea surface (water) temperature (SST) dataset with a global land surface air temperature dataset into this merged dataset of both the Earth land and ocean surface temperatures. The SST dataset is the Extended Reconstructed Sea Surface Temperature (ERSST) version 3b. The land surface air temperature dataset is similar to ERSST, but uses data from the Global Historical Climatology Network Monthly (GHCNM) database. The data were produced by and are archived at the NOAA National Centers for Environmental Information (NCEI).
