One heatwave. Many cities. Thousands of thermal insights. During the recent European heatwave, constellr monitored cities across the continent, including Madrid, Rome, Brussels, Helsinki, Klagenfurt, Zaragoza, Athens, Palma de Mallorca, Kraków, and Toulouse, capturing how urban environments responded to extreme temperatures. Looking across these cities reveals something fascinating: no two urban landscapes behave the same. From space, thermal imagery helps us understand how different types of infrastructure interact with heat. Dense city centres, industrial zones, airports, roads, parks and water bodies all heat up and cool down at different rates. The thermal patterns also reveal how urban design, building materials and vegetation influence heat retention and cooling throughout the day. Comparing multiple cities allows us to identify common trends as well as local differences, providing valuable evidence for climate adaptation, infrastructure resilience and more informed urban planning. As a Copernicus Contributing Mission, constellr delivers operational thermal monitoring that supports cities and public authorities with timely, high-resolution surface temperature intelligence. We're proud to contribute to Europe's efforts to build more climate-resilient cities together with Copernicus ECMWF, European Environment Agency, ADEME, and our partners across Europe. Which city stands out to you? What thermal patterns can you spot?
