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.
The SMOS Wind Data Service provides, in near real time (NRT), surface wind speed over the ocean derived from the brightness temperature measurements of SMOS.
