Description:

Air quality remains a significant public health challenge facing large fractions of the population in the U.S. and globally.  Variations in meteorology and climate couple with a range of source types and activity levels to yield a wide range of regional scale air quality issues.  This session solicits submissions from observational and modeling studies on air pollution in different regions within North America and around the world.  Observational studies that include remote sensing, in-situ measurements, analysis from recent field intensives or a combination of these approaches are encouraged.  Laboratory studies for understanding of important atmospheric chemical processes and progress toward the development of chemical mechanisms are also of interest. Modeling studies that use observations and laboratory data to improve predictive skills of air quality are welcome. Relevant air quality issues include, but are not limited to, ozone, fine particles, smoke from wild and prescribed fires, visibility, regional haze and inequalities in pollutant distributions.
