World UTCI and MRT

A "new" database has been made available by the EU, from the Copernicus project (free access, login required).

UTCI and T_{MRT} , August 31st, 2018


This dataset provides a complete historical reconstruction of the UTCI (Universal Thermal Confort Index, a thermal comfort index as well as the MRT (Mean Radiant Temperature, essential for the thermal comfortestimation), from 1979 up to today. Those parameters are computed by the ERA5-HEAT (Humen thErmAl comforT) model. It is based upon a reanalysis of observations from across the world, to provide a globally complete and consistent description of the Earth’s climate and its evolution in recent decades.
