A Guide to Aeolus Range Bin Settings

Launched on 22 August 2018, Aeolus is the first satellite mission to acquire profiles of Earth’s wind on a global scale. After almost two years in space, its near-real time observations have been assimilated into the Numerical Weather Prediction (NWP) models of several European meteorological services, like ECMWF, Météo-France and DWD, and have proven crucial when the grounding of airplanes during the COVID-19 pandemic led to a sharp decrease in meteorological observations.

EO Level1 Lessons Learned Workshop

As a result of a recommendation at the Atmospheric Composition Validation and Evolution workshop held on 13-15 March 2013, representatives from the atmospheric composition and optical Level 1 communities participated in a meeting in June 2013 to discuss how to integrate the latest findings on Level 1 activities into the upcoming reprocessing campaigns of ERS1/ERS-2/Envisat and to support scientific research, the EO applications and exploitation community, ESA programmes, to prepare for the Sentinels operations phase and draw together lessons learned for future missions. The presentations and the meeting report are available below.
