The overall objective of the ESC Geomagnetic Conditions - definition and development activities work is to ensure operational and development activities within the Geomagnetic Conditions Expert Service Centre (G-ESC) of ESA's Space Situational Awareness (SSA) Space Weather (SWE) network.
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.
Heavy rainfall has triggered flooding in southern Iran, particularly in the Sistan and Baluchestan, Hormozgan and Kerman provinces. The downpour has led to blocked roads and destroyed bridges, crops and houses – displacing thousands of people.
ESA's Aeolus satellite has been returning profiles of Earth's winds since 3 September 2018, just after it was launched – and after months of careful testing these measurements are considered so good that the European Centre for Medium-Range Weather Forecasts is now using them in their forecasts.
While news of COVID-19 dominates headlines and many of us practice social distancing, there still remains the need for action on climate change - and satellites are vital in providing the key facts on this global issue.
