Simulating the future of Arctic climate is strongly limited by inadequate descriptions of regional feedback mechanisms in models involving the ocean, sea ice, snow cover, clouds and radiation, and importantly marine biology.

These feedbacks must be described in parameterized form in climate models as functions of resolved-scale parameters. Quality and climate sensitivity of any climate model are critically dependent on these parameterizations that rely on adequate and extensive observations both to formulate and test them.

The underlying motive and overall objective of the proposed program will be to provide unique high quality data to understand and quantify the processes that control the properties and evolution of the aerosol-cloud system in the high Arctic region relevant to radiative forcing and sea ice-melt.

In the program focus is a multi-month high Arctic field experiment employed on the Swedish icebreaker Oden from mid-July through September 2018. An integrated approach will reach from the upper-ocean through the sea-ice into low clouds. The program comprises state-of-the-art multi-disciplinary scientific contributions from scientists in marine physics, chemistry and biology, boundary layer meteorology, atmospheric chemistry and physics. The outstanding value of such an interdisciplinary approach has been demonstrated by the well-documented progress of 5 previous Swedish research over the Arctic pack ice in summer, starting with the Ymer-expedition in 1980.
