Focus

The Cloud and Aerosol Processes program in the Chemical Sciences Division studies processes of importance to climate, air quality, and precipitation.

Measurements

We measure the chemical, physical, and optical properties of aerosol particles from aircraft, ships, and ground sites as well as in the laboratory. By combining these with gas-phase and other measurements, we learn about the sources, sinks, and radiative properties of these particles. We also collaborate with aircraft measurements of cloud droplets.

Modeling

We model the physical and radiative properties of clouds, including large eddy simulation models, mesoscale models, and detailed models of cloud chemistry. These model results are compared to in-situ and remote sensing data.

Collaborations

We participate in regional and global scale studies of aerosol and cloud properties from satellite data and monitoring networks. These studies lead to improved understanding of atmospheric processes with a strong emphasis on communicating this understanding through scientific publications, assessments, and development of instrumentation and modeling tools.
