Within the IDEAS-QA4EO ESA project a precision filter radiometer (PFR) travelling standard was installed at the European calibration site of AERONET to provide continuous traceability of aerosol optical depth measurements to the World reference maintained at Davos through a PFR Triad.
ESA's Earth Observation Programme Board has unanimously approved the integration of the Federated Satellite Systems (FSSCat) mission, the Geostationary Environment Monitoring Spectrometer (GEMS) instrument on-board the GEO-KOMPSAT-2B satellite and the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission, as Third Party Missions.
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.
Ferocious bushfires have been sweeping across Australia since September 2019, fuelled by record-breaking temperatures, drought and wind. The country has always experienced fires, but this season has been horrific.
