Preparations for the launch of the new Earth observation satellite EarthCARE (Earth Cloud Aerosol and Radiation Explorer) at the end of May are in full swing. The joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) will measure clouds, aerosol and radiation more accurately than ever before. This will be made possible by linking four state-of-the-art instruments.

Leipzig. The smoke from the extreme forest fires on the US West Coast in September 2020 travelled over many thousands of kilometres to Central Europe, where it continued to affect the atmosphere for days afterwards. A comparison of ground and satellite measurements now shows: The forest fire aerosol disturbed the free troposphere over Leipzig in Germany as never before. An evaluation by an international research team led by the Leibniz Institute for Tropospheric Research (TROPOS) revealed an extraordinary optical thickness on 11 September 2020, which attenuated sunlight by a third.
