New insights into the formation of tiny cloud particles in the Arctic - EurekAlert
Mobile measuring devices enable the research of atmospheric processes in higher air layers that have not yet been recorded by conventional measuring stations on the ground. The airborne flight systems therefore make an important contribution to research into the causes of climate change in the Arctic. A team of German researchers has combined two of these methods over Spitsbergen in recent weeks: Simultaneous measurements of meteorological parameters and minute aerosol particles were carried out using a tethered balloon system and an unmanned aircraft. Several cases have already been observed in which these new formation processes took place at higher altitudes, sometimes even between cloud layers, and were therefore invisible to ground stations. These particles can, for example, influence the formation of clouds and thus have an impact on climate change. However, the reason why the Arctic is warming much faster than other regions of the world is still unclear.
