We are pleased to announce that the new C3S application Thermal Trace has been launched today, 20 August 2025:
thermaltrace.climate.copernicus.eu
Thermal Trace is an interactive web-application to explore heat and cold stress data anywhere on Earth from 1940 up to 5 days behind real time.
It provides maps and charts related to feels-like temperature and thermal stress and provides historical context to explore changes through time.
Number of days with at least ’strong heat stress’ during 2024 in Europe, and bar chart showing the number of very strong and extreme heat stress days during each year from 1940 to 2024 in Athens.
