Midwest and Central States Air Quality Workshop

April 22-24, 2014
Drury Plaza Hotel at the Arch
St. Louis, MO

Meeting Objective: The Workshop brought together air quality researchers who have a focus on the central and midwestern portions of the U.S., technical state agency staff, and federal regulatory agency staff to share current research, methodologies, and projects. Session topics included emissions, data analyses, and modeling.
