Meteodrones are cutting-edge weather drones designed to close the critical data gap in the lower and middle atmosphere. Engineered in Switzerland, these autonomous flying platforms capture high-resolution, real-time weather data—such as temperature, humidity, pressure and wind—at altitudes up to 6 km. By collecting hyperlocal vertical profiles, Meteodrones significantly improve short-term forecasts and nowcasts, especially for fog, thunderstorms, icing and other local phenomena that traditional systems often miss. With de-icing capabilities, remote operation via Meteobase, and seamless integration into weather models like EURO1k, Meteodrones set a new standard for precision meteorology across aviation, agriculture, energy and climate research.
