Discover the latest news on the European Space Agency's Earth Observation activities. Learn all about new data availability and how ESA's missions are performing.
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.
Aeolus’s telescope requires periodic collimation and refocussing. To this end, the Instrument Telescope Refocussing activity aims to improve the radiometric performance of the Atmospheric Laser Doppler Instrument (ALADIN)’s telescope by optimizing the throughput at the field stop, the smallest aperture where the return light has to pass. This is done through a change of the temperature settings on the telescope.
Strateole-2 is a French-US project supported by ESA that uses CNES superpressure balloons drifting around the globe to study the climate processes in the Tropical Tropopause Layer (TTL) and the lower stratosphere, helping Aeolus validation activities along the way.
The release of Aeolus data to the public was made possible by the product optimisation work performed by the Aeolus DISC.
Due to a scheduled maintenance, access to the Aeolus dissemination system will be unavailable on 5 May.
