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.

EVENT - Conference
The 8th International Conference on Remote Sensing and Geoinformation of Environment (RSCy2020), due to take place from 16 to 18 March 2020, has been postponed until further notice.
EVENT - Conference
This meeting has been replaced by EGU2020: Sharing Geoscience Online initiative, a series of online activities. The EGU General Assembly aims to bring Geo-Scientists from all over the world to one meeting covering all disciplines of the Earth, planetary and space sciences.
EVENT - Workshop
The Copernicus Sentinel-5 Precursor Validation Team Workshop will take place in Frascati (Rome), Italy from 11 - 14 November 2019.
Explore the many instruments the European Space Agency use to observe the Earth. ESA offer data from a wide range of optical, radar, atmospheric, altimetric and gravimetric instrumentation.
Learn about the ground-based, ship-borne, balloon-borne, and airborne campaigns and small satellite field experiments that validate orbiting ESA EO satellites and support future mission development.
