Welcome to the Cappa Group webpage. We are part of the Department of Civil and Environmental Engineering and the Atmospheric Science Graduate Group at the University of California, Davis.

Understanding how the properties of aerosols in the Earth's atmosphere vary in both space and time is of great importance owing to their influence on global climate, precipitation, visibility and human health.
Our research focuses on characterization of the chemical, physical and optical properties of atmospheric aerosols, both through laboratory experiments and field observations.
