Dataset
EUSTACE: Global land station daily air temperature measurements with non-climatic discontinuities identified, for 1850-2015, v1.1
Abstract
This dataset consists of a global collection of land surface air temperature data from meteorological stations covering the period from 1850-2015. It has been compiled as part of the European Union Horizon 2020 EUSTACE (EU Surface Temperature for All Corners of Earth) project. This version 1.1 is an update to the v1.0 dataset that fixes a bug in the time values in the original files; the data is otherwise identical.
The dataset provides daily maximum and minimum temperatures from stations globally, brought together from a number of public databases: Global Historical Climatology Network Daily Temperatures (GHCN-D); European Climate Assessment & Dataset (ECA&D) non-blended; International Surface Temperature Initiative (ISTI); DECADE (Data on Climate and Extreme weather for the Central Andes); and ERA-CLIM (European Reanalysis of Global Climate Observations). These data have then been quality controlled through the removal of duplicates and unreliable data sources, and come with a large amount of additional information on quality, homogeneity and resolution.
These data are available for non-commercial use.

Process overview
| Title | Derivation of the EUSTACE land station daily air temperature measurements with non-climatic discontinuities identified |
| Abstract | The EUSTACE dataset, 'Global land station daily air temperature measurements with non-climatic discontinuities applied, for 1850-2015', has been produced by bringing together daily maximum and minimum temperatures from various public databases (GHCN-D, ECA&D, DECADE, ISTI and ERA-CLIM). These data have then been quality controlled through the removal of duplicates and unreliable data sources, and were assessed for homogenity by applying tests to look for breakpoints in the time series. For further details see the EUSTACE product user guide. The following datasets have been used as input: |
