C11D:
Chemical Exchange between Air, Snow, and Ice: From the Micro to the Global Scale I

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 17540

Session Description:
Snow and ice surfaces and their chemical interactions with the atmosphere are key to understanding polar atmospheric composition, climate, and ice core records. Analysing climate change in the polar regions requires a better integration of lab and field studies to improve model parameterisations and quantify impacts of Air-Snow-Ice exchange from local to global scales. This session is intended to provide an inter-disciplinary forum for researchers working on micro-scale properties and/or processes in snow and ice, polar tropospheric chemistry (oxidation capacity, ozone, halogens, nitrogen and carbon cycling, mercury), aerosol processes coupled to surface interactions, and biogeochemistry of sea ice, as well as links to clouds and climate of the high latitudes. Submissions with a focus on recent change in sea ice or mid-latitude snowpacks are welcomed.
