Europe's first geostationary sounder satellite is launched

Summary

Extreme weather events like storms, flooding, and heatwaves have caused hundreds of billions of euros in damage and claimed tens of thousands of lives across Europe in the past decades. Launched on 1 July 2025, MTG-S1 will provide Europe’s national meteorological services with high-frequency data on temperature, humidity and trace gases throughout the atmosphere – enabling forecasters to detect the earliest signs of severe weather, extend the lead times of weather warnings, improve forecasting, and help protect lives and property.Phil Evans, Director-General of EUMETSAT, said: “MTG-S1 will provide entirely new types of data products that will support specialists across EUMETSAT member states in detecting signs of atmospheric instability even before clouds begin to form. Combined with data from the MTG imaging satellites, it will, for the first time, offer a space-based view of the full lifecycle of convective storms. This will provide tremendous support to national meteorological services in carrying out their vital work, helping to save lives, reduce disruption, and strengthen resilience.“The effects of the climate crisis are not distant threats: they are already being felt across Europe – through more frequent storms, longer heatwaves, and shifting climate patterns. MTG-S1 will support more timely warnings, safer travel decisions, more effective emergency response, and support informed action.“My sincere thanks go to everyone who made MTG-S1 possible – our teams at EUMETSAT, our member states, the European Union, the European Space Agency, national meteorological services, and all our industrial and academic partners. This successful launch is a testament to the strength of European cooperation. We now look forward to moving to the next phases and preparing the satellite for full operations.”A forecasting revolutionMTG-S1 is the first geostationary meteorological sounder satellite to fly over Europe and carries two key missions: the Infrared Sounder and the Europe...
