| Summary: | (ASCOS, www.ascos.se) investigates the physical and chemical processes leading to cloud formation in the high Arctic Ocean. This work examined a potential contribution of particles emitted from open leads to the Arctic aerosol using flux and gradient measurements made from an ice floe in the Arctic pack ice. The Arctic sea-ice has been identified as an important tipping element in the Earth’s climate system (e.g. Lenton et al., 2008) with potentially large implications for Europe and the rest of the world. However, current regional and global climate models lack many relevant cloud-ice-ocean feedback mechanisms. From earlier observations, a local natural biogenic source of aerosol particles from |
