Session 4 Pollutant Sources, Transport, Transformation, and Sinks

Thursday, 14 January 2016: 11:00 AM-12:15 PM
Room 356 ( New Orleans Ernest N. Morial Convention Center)
Host: 18th Conference on Atmospheric Chemistry
Jeffrey L. Collett Jr., Colorado State University, Atmospheric Science Department, Fort Collins, CO

Anthropogenic emissions to the atmosphere can result in substantial adverse impacts to human health and the environment. Understanding the nature and magnitude of these impacts requires knowledge of pollutant source emissions, the transport and physical/chemical transformation of those emissions in the atmosphere, and sinks for their eventual removal. This session will focus broadly on these topics for primary and secondary gas and particle phase pollutants. Transport over local to global scales; transformations via gas phase, aqueous phase, and heterogeneous processes; and removal by dry and wet deposition processes are all of interest. Presentations that examine combinations of emissions, transport, transformation, and/or deposition processes are of particular interest. Student participation is especially encouraged. Students giving first author posters or platform presentations will be eligible to compete for cash prizes and certificates from AMS.
