This manuscript discusses the basis and uncertainties of the Aeolus mission performance and its improvement over time. Aeolus is a key ESA mission for atmospheric dynamics, greatly beneficial for numerical weather prediction and Earth system dynamics studies. The lessons learned in understanding and improving the atmospheric measurement technique described here will be of great importance for the Aeolus follow-on mission, now being planned by EUMETSAT and ESA in Europe.
Short summary
In August 2018, the first wind lidar Aeolus was launched into space and has since then been providing data of the global wind field. The primary goal of Aeolus was the improvement of numerical weather prediction. To verify the quality of Aeolus wind data, DLR performed four airborne validation campaigns with two wind lidar systems. In this paper, we report on results from the two later campaigns, performed in Iceland and the tropics.
