Changes are occurring rapidly in the Arctic atmosphere due to a range of influences, including changing composition, changing sea-ice, changing interactions with lower latitudes, and changing inputs from the land, snow, ice and oceans. The interactions and processes driving these changes are complex and varied, but are also important to understanding the entire Arctic system. This session invites papers on all aspects of the Arctic atmosphere including measurements, instrumentation, research sites, modeling efforts, and especially new insights into this complex and important atmospheric system from short-term and longer-range studies
