Aerosol Cloud



We investigate the formation, composition, and measurement of anthropogenic and biogenic aerosol to explore the impacts on foremost climate and subsequently health. Understanding aerosol-cloud-climate interactions is imperative to our predictive understanding of climate. Atmospheric particulate matter, or aerosol can either directly reflect incoming solar radiation to space, the “direct” effect , or affect the hydrological cycle by modifying cloud microphysical processes, the “indirect” effect. Aerosols that can uptake water and form droplets are called Cloud Condensation Nuclei (CCN) and their thermodynamic properties are important for constraining the global aerosol-indirect effect. Our research laboratory strives to quantify the links between anthropogenic and biogenic CCN chemistry and physics that also influence air quality and health.
