Global baseline datasets
From Glossary of Meteorology
global baseline datasets
Datasets designed to provide a complete historical record of the climate.
Such datasets include parameters such as surface air temperatures, sea surface temperatures, tropospheric and stratospheric temperatures, atmospheric water vapor, and radiative fluxes at the top of the atmosphere. For maximum value, such datasets should be designed to minimize the inhomogeneities associated with changes in instrumentation, instrument exposure, or observing techniques.
