Record Heat Across Europe
June 2024 has brought unprecedented temperatures to the continent. Several cities are under red alert, and on 23 June France recorded its hottest June day on record.
Satellite View of Land Surface Temperature
On the same day, the Copernicus Sentinel‑3 satellite captured an image of the Earth's surface. Unlike air temperature, the instrument measures the temperature of the ground, which can be considerably higher as rocks and asphalt store solar heat throughout the day.
Technology Behind the Measurements
Sentinel‑3 carries thermal infrared sensors that continuously monitor temperature data from land, oceans, ice and the atmosphere. These observations support both short‑term weather response and long‑term climate monitoring.
Implications for the Public
The recorded surface temperatures explain why heatwaves pose heightened health risks, especially in urban areas. Authorities can use the data to refine heat‑action plans and protect infrastructure.
Looking Ahead
The Sentinel‑3 mission will keep delivering essential information to understand the interplay of weather, climate and human activity. Ongoing analysis will track how surface temperatures evolve over the summer and inform necessary adaptation strategies.
