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