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.
In the last decade, climate change has taken centre stage in both the public and scientific arenas, as increasingly extreme weather and human impact on the environment have become more apparent.
announcement of opportunity
ESA's Climate Change Initiative is pleased to announce a call for post-doctoral research fellowship proposals. Early-career researchers interested in the fields of earth observation and climate are invited to submit project proposals to implement leading-edge research that contributes to the aim of the Climate Change Initiative (CCI) programme.
Since the saltiness of ocean surface waters is a key variable in the climate system, understanding how this changes is important.
As ESA's SMOS satellite celebrates 10 years in orbit, yet another result has been added to its list of successes. This remarkable satellite mission has shown that it can be used to measure how the temperature of the Antarctic ice sheet changes with depth – and it's much warmer deep down.
