Investigations of the atmosphere by means of unmanned mini-airplanes can contribute significantly to the investigation of the causes of Arctic climate change, as they provide an insight into ground-level air layers that are not monitored by other measuring stations. This is the conclusion drawn by a German research team from current measurements that have just taken place on Spitsbergen. It was possible to observe the formation of new particles in the air, which can later evolve to clouds and have an influence on climate change. It is still not understood in detail why the Arctic is warming more than twice as strong as other regions of the earth. The measurement campaign on Spitsbergen, which will run until the end of May, was the first joint deployment of mini research aircraft developed in Germany in a polar region.
