Abstract

This paper will describe the current status of instrument pre-development activities that are being performed in the frame of a potential Aeolus Follow-On mission (Aeolus-2). The main inputs for a future Doppler Wind Lidar (DWL) instrument that have been used are: lessons learned from the Aeolus development phases and the in-orbit operations and performance; initial inputs from EUMETSAT including a total mission lifetime of 10-15 years utilizing 2-3 spacecraft with a launch of the first satellite in 2029, increased robustness and operability of the instrument, and an emphasis on reduction of recurrent costs; the maximum utilization of the demonstrated design heritage; and a number of recommendations for the requirements of a future DWL mission from the Aeolus Scientific Advisory Group. These inputs have been collated and combined into a set of preliminary requirements which have been used as the basis for a dedicated Instrument Consolidation Study. The aim of the study is to adapt the design (taking account of the heritage retention principle), in order to improve the performance of the instrument for the Aeolus follow-on mission. In addition, three instrument subsystem pre-development activities have been kicked-off: two laser transmitter engineering model pre-developments aiming at increasing the output energy level up to 150mJ in UV and the robustness of the laser transmitter and the pre-development of an improved detector with better vertical sampling. These developments have the aim to demonstrate that issues identified from the above are resolved and that the technology levels are sufficiently mature for the follow-on DWL mission.
