Abstract
We highlight some of the scientific benefits of the Aeolus Doppler Wind Lidar mission since its launch in August 2018. Its scientific objectives are to improve weather forecasts and to advance the understanding of atmospheric dynamics and its interaction with the atmospheric energy and water cycle. A number of meteorological and science institutes across the world are starting to demonstrate that the Aeolus mission objectives are being met. Its wind product is being operationally assimilated by four Numerical Weather Prediction (NWP) centres, thanks to demonstrated useful positive impact on NWP analyses and forecasts. Applications of its atmospheric optical properties product have been found, e.g., in the detection and tracking of smoke from the extreme Australian wildfires of 2020 and in atmospheric composition data assimilation. The winds are finding novel applications in atmospheric dynamics research, such as tropical phenomena (Quasi-Biennial Oscillation disruption events), detection of atmospheric gravity waves, and in the smoke generated vortex associated with the Australian wildfires. It has been applied in the assessment of other types of satellite derived wind information such as atmospheric motions vectors. Aeolus is already successful with hopefully more to come.

Bibliographical note
Funding Information:The European Space Agency’s (ESA) Aeolus satellite mission is the world’s first spaceborne Doppler Wind Lidar (DWL), providing profiles of Horizontal Line-Of-Sight (HLOS) wind retrievals and UV (Ultra-Violet) optical properties profiles [1]; [2]; [3]. Aeolus partially fills a gap in the global observing system for global direct wind profile measurements [4]; [5]. It has already successfully demonstrated the suitability of space-based Doppler Wind lidar technology for operational Numerical Weather Prediction (NWP), and there is an increasing list of benefits for atmospheric sciences being confirmed and further discovered. The good data quality that has been achieved to allow these benefits is in a great part due to the efforts of the thorough pre-launch preparations of the Aeolus on-ground data processing and monitoring and the in-flight instrument and data analysis and data processing improvements by the Aeolus Data Innovation and Science Cluster (DISC) in collaboration with ESA. This work has also been supported by further invaluable contributions from the Aeolus CAL/VAL and science teams in Europe and across the world. This paper briefly reviews some of the important benefits found.
