Joint Session 49 Joint Session with the Committee on Atmospheric Chemistry. Part III: Quantification of Long-Range Transport of Air Pollutants

Thursday, 11 January 2018: 8:30 AM-9:30 AM
412 (Hilton) (Austin, Texas)
Hosts: (Joint between the 20th Joint Conference on the Applications of Air Pollution Meteorology with the A&WMA; and the 20th Conference on Atmospheric Chemistry )
Stefano Alessandrini, NCAR, RAL, Boulder, CO and Terry Keating, Office or Air and Radiation, U.S. Environmental Protection Agency, Office of Air and Radiation, Washington, DC

It is now well recognized that international and global flows of pollutants contribute to ozone and aerosol pollution observed at the regional and local scales.  However, quantifying the contribution of the long-range transport to observed air pollution and exceedances of ambient standards continues to be a scientific challenge. This session will explore recent and ongoing work to quantify extra-regional contributions to exceedances of air quality standards using global and regional models and the analysis of ground-, aircraft-, and space-based observations. The session will also explore projections of how international and global flows of pollutants are expected to change as a result of changes in global emissions and climate.
