ESA Earth Observation Mission: Aeolus measures the wind

Press release, 20.08.2018

On 21 August 2018, the European Space Agency (ESA) will launch the scientific Earth observation mission Aeolus. The aim of the mission is the global mapping of wind profiles in the atmosphere. These observations, together with information about aerosols and clouds, contribute to an improved understanding of the dynamic processes in the atmosphere and are of great importance for weather forecasting.

The only instrument on the satellite is a high-precision laser system with which wind speeds can be measured at different heights. Swiss companies have made significant contributions to the mission as part of ESA's development programme.
