Title: “Dusty Skies and Dirty Buildings: Adventures in Atmospheric Photochemistry”

Abstract:

Over a billion tons of photoactive dust are released into the atmosphere every year from deserts and other arid environments. After emission, this dust undergoes transport to distant urban regions, where it can mix with local pollution sources and settle on building surfaces, which are themselves potential substrates for photochemistry. Although studies have shown that reactions on environmental surfaces can influence the lifetime of surface-sorbed pollutants and the atmospheric abundance of reactive trace gases, our understanding of photochemistry on dust and urban surfaces is far from complete. In this seminar, I will outline our group’s approach to studying these complex systems, and highlight some of our recent discoveries.
