TLDR
In this article, the European Space Agency (ESA) decided to implement a Doppler wind lidar mission called the Atmospheric Dynamics Mission Aeolus (ADM-Aeolus) to demonstrate the potential of the doppler lidar technology and the expected impact on numerical weather forecasting.Abstract:
The global observation of profiles of the atmospheric wind speed is the highest-priority unmet need for global numerical weather prediction. Satellite Doppler lidar is the most promising candidate to meet the requirements on global wind profile observations with high vertical resolution, precision, and accuracy. The European Space Agency (ESA) decided to implement a Doppler wind lidar mission called the Atmospheric Dynamics Mission Aeolus (ADM-Aeolus) to demonstrate the potential of the Doppler lidar technology and the expected impact on numerical weather forecasting. An airborne prototype of the instrument on ADM-Aeolus was developed to validate the instrument concept and retrieval algorithms with realistic atmospheric observations before the satellite launch. It is the first airborne direct-detection Doppler lidar for atmospheric observations, and it is operating at an ultraviolet wavelength of 355 nm. The optical design is described in detail, including the single-frequency pulsed laser and th...read more

Rayleigh-Brillouin Scattering in Binary-Gas Mixtures.
TL;DR: In this article, the spectral line shape of spontaneous Rayleigh-Brillouin scattering in mixtures of the noble gases Ar and Kr, with He, was analyzed. But He is merely a spectator atom: it affects the relaxation of density fluctuations of the heavy constituent, but its contribution to the scattered light intensity is negligibly small.

TL;DR: A detailed characterization of the hot pixels that occurred during the first 1.5 years in orbit of Aeolus is provided and it is shown that multi-level RTS pixels with high fluctuation are the biggest challenge for the hot pixel correction scheme.
