Abstract
The ASCOS (Arctic Summer Cloud Ocean Study) expedition was carried out during summer 2008 in high-latitude areas in the Arctic Ocean. With the Swedish icebreaker Oden serving as the research platform, a range of scientific investigations were made. The main target was to study the formation and life cycle of low-altitude Arctic clouds in the central Arctic. The expedition was interdisciplinary and covered observations of the physics and chemistry of the atmosphere and the upper ocean, meteorology, cloud microphysics and aerosols, and upper-ocean biogeochemistry. Several of these datasets are available here.
