We aim to improve our understanding of the chemical composition of the atmosphere, and how it is influenced by human activities and natural processes. We use a combination of field observations (via our ground station, mobile lab, and aircraft) and atmospheric modeling to investigate the origins, chemistry, and transport of key air pollutants, and their implications for air quality and climate. Current research projects focus on urban photochemistry in the Intermountain West, the air quality impact of wildfire smoke, and emissions of prescribed burning.
