Metadata describing the datasets used for the project HHS-EWS (European Research Council Proof-of-Concept Grant No. 101069213). It includes mortality data for several European countries, gridded population data, population data from Eurostat, temperature data, and weather forecasts.

The aim of HHS-EWS is to create a novel operational early warning system for environmental temperatures that incorporates the real risks to people's health, especially that of the most vulnerable populations. The system will transform the predictability of atmospheric variables into health predictions using epidemiological models specifically designed for the most vulnerable social groups. HHS-EWS is funded by the ERC Proof-of Concept scheme, which is intended to transform the theoretical research of the parent project into high-risk but potentially high-benefit innovations. In this case, the innovation aims to increase society's resilience to climate change, building on the theoretical research in epidemiology and social sciences being carried out in the context of EARLY-ADAPT (European Research Council Consolidator Grant No. 865564).
