For the first time, an international research team led by the Leibniz Institute for Tropospheric Research (TROPOS) has investigated atmospheric ice-nucleating particles (INPs) in ice cores, which can provide insights on the type of cloud cover in the Arctic over the last 500 years. These INPs play an important role in the formation of ice in clouds, and thus have a major influence on the climate. So far, however, there are only a few measurements that date back only a few decades. The new method could provide information about historical clouds from climate archives and thus close large gaps in knowledge in climate research.
