A22F:
Tropospheric Chemistry in Polar Regions: Sources, Transport, Processes, and Impacts 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#: 16472

Session Description:
Tropospheric chemistry in the polar regions affects the Earth through processes ranging from boundary layer interactions to intercontinental transport, and over temporal scales from seconds to years. The emission, transport and deposition of both natural and anthropogenic gases and aerosols has consequences for biological systems, human health, and global climate. Both stark differences and surprising similarities occur in the in the atmospheric and chemical processes in the cold regions surrounding the two poles. This session invites submissions related to all aspects of polar tropospheric chemistry, including observational, modeling, and laboratory studies of all phases, as well as to climatic, ecological and societal impacts of these processes.
