Abstract

This dataset contains matched in situ reference and EUSTACE temperature estimates used in the validation of version 1.0 of the EUSTACE Globally gridded clear-sky daily air temperature estimates from satellites product and the version 1.0 EUSTACE Global daily air temperature product. The data are made available to allow traceability of the validation. This dataset has been compiled as part of the European Union Horizon 2020 EUSTACE (EU Surface Temperature for All Corners of Earth) project.

Note that due to the licensing conditions of some of the validation datasets this data is made available for non-commercial purposes only. Additionally some of the datasets used in validation of the ice data do not allow onward redistribution, so only the ocean and land data have been included in this dataset.

Title Derivation of the EUSTACE coincident daily air temperature estimates and reference measurements, for validation
Abstract To validate the EUSTACE globally gridded clear-sky daily air temperature estimates from satellites and the the EUSTACE global daily air temperature product a set of match-up datasets containing in-situ reference and EUSTACE temperature estimates have been produced. The matchups were produced separately for each test-reference dataset pairing. Therefore each file contains only matchups of one EUSTACE product to one in situ dataset. The matchup process varied between platforms and as a consequence the filename format, file format and variables contained within each file depend on the matched datasets.
