29 September 2017 AEOLUS mission: the latest preparations before launch
Author Affiliations +
The European Space Agency is developing a direct detection Doppler Wind Lidar for measuring wind profiles from space. The main objective of Aeolus is to provide tropospheric and lower stratospheric wind profiles globally for the improvement of weather forecast on short and medium term. Aeolus data are expected to greatly contribute to weather and air quality monitoring and to scientific advances in atmospheric dynamics. The UV Lidar instrument, ALADIN, will deliver horizontally-projected single line-of-sight wind profiles from the Doppler shift of molecular and particle backscatter. The development of the AEOLUS mission passed a major milestone with the integration of the full instrument and its functional and performance tests in 2016 and a 6-month life test of the spare UV laser transmitter. The satellite has been assembled and has successfully been subjected to a programme of functional and environmental (vibration, acoustic, shock, EMC) tests. The preparation of thermal vacuum testing, including instrument performance in vacuum, is close to completion.
