Research Emissions Air Quality Climate Ecosystem Impacts Policy People Faculty Students Research Staff Education Undergraduate Graduate Prospective Resources Computational Laboratory Field Work Events Emissions Gases and particles are emitted into the atmosphere from a wide range of sources, from tailpipes to trees. Understanding what drives these emissions and how they respond to changes in climate and human activity is a key area of atmospheric chemistry. READ MORE Air Quality Once emitted into the atmosphere, gases and particles in the atmosphere undergo complex chemical transformations and these pollutants can be transported great distances down-wind, impacting air quality both locally and intercontinentally. READ MORE Climate Gases and particles in the atmosphere interact with radiation and clouds to fundamentally alter the Earth’s climate. In turn, the climate can drive changes in atmospheric composition and global biogeochemical cycles. READ MORE Ecosystem Impacts What goes up must come down! The atmosphere can transport both chemical nutrients and toxic substances far from sources, impacting ecosystem health around the world. READ MORE Policy The science of atmospheric chemistry is of critical relevance to the sphere of policy and regulation, where it can be harnessed to effectively protect human and environmental welfare. READ MORE Building on research in the Selin Group, The Mercury Game, a role-playing simulation, is a teaching tool designed to help students better understand science-policy interactions for atmospheric chemistry issues LEARN MORE This year’s Traveling Research Environmental eXperience (TREX) found Professors Jesse Kroll and Colette Heald working with 14 undergraduate students measuring (AND chasing!) volcanic smog (vog) on the Big Island of Hawaii.
