A11C:
Arctic Tropospheric Composition:  Natural and Anthropogenic Emissions, Transport, Processing, and Fate of Trace Gases and Aerosols I Posters


Session ID#: 8426

Session Description:
Recent studies have demonstrated the need to improve knowledge of the processes that govern trace gas and aerosol budgets in the Arctic region.  Atmospheric processes determine the concentrations of short-lived climate forcers, which have contributed to the rapid warming of the Arctic over recent decades. Understanding the lifecycle of trace gases and aerosols in the Arctic is also important because they influence air quality, leading to negative impacts on human health and vulnerable ecosystems, and contribute to important chemistry-climate interactions.  The multiple time and spatial scales of emissions, transport, chemical and physical processing, and deposition processes requires the use of long term observations, focused observational data, laboratory studies, and modeling at multiple scales.  This session invites research on natural and anthropogenic sources and cycling of trace gases and aerosols in the Arctic region.  Contributions from a wide variety of research perspectives are encouraged.
