ESA’s ADM-Aeolus wind mission will provide timely and accurate profiles of the world’s winds and further information on aerosols and clouds. The mission will advance our understanding of atmospheric dynamics. It will also provide much-needed information to improve weather forecasts and contribute to climate research. The satellite carries a single instrument: a Doppler wind lidar called Aladin. This sophisticated instrument is designed to probe the lowermost 30 km of the atmosphere along the satellite’s orbital path. Comprising a powerful laser, a large telescope and a very sensitive receiver, Aladin is the first wind lidar in space. In cloud-free air the lidar will probe the atmosphere down to the surface of Earth, or to the top of dense cloud. Data on wind will be ingested in weather models to improve forecasts. Improved weather forecasts have considerable socio-economic benefits, in particular for extreme weather events. For example, the better prediction of the strength and path of an evolving hurricane system is important for local emergency management.
