This session is intended to provide an interdisciplinary forum to bring together researchers working in the areas of high-latitude meteorology, chemistry, oceanography, and climate. The emphasis is on the role of boundary layer processes that mediate exchanges between the Earth's surface (snow, ice, ocean and land) and the atmosphere. We invite contributions in the following areas:

(1) Results from field programs and observatories, insights from laboratory studies, and advances in modeling and reanalysis
(2) Surface processes involving snow, sea-ice, ocean, land/atmosphere chemical exchange
(3) External controls on the boundary layer such as clouds and transport processes
(4) The role of boundary layers in polar climate change and implications of climate change for surface exchange processes, especially in the context of reduced Arctic sea ice and physical and chemical changes associated with an increasing fraction of first year ice.

Given the interdisciplinary nature of this session, we encourage all presentations to start by briefly explaining how their work relates to the broader context. In past years we have requested a schedule where poster sessions follow oral sessions to allow for oral poster introductions. For those who indicate a `no preference` request for the presentation style, we encourage a poster supplement to allow for further discussion.
We would like to encourage young scientist/student presentations by reserving several oral units per session for such papers.
