Aerosol Properties & Processes

Research Highlight Climate: Global airborne mission finds a belt of particle formation is brightening clouds. Clouds alter Earth's radiative balance, depending on how bright they are, and starts a process that may occur over 40 percent of the Earth's surface, which may mean today's climate models underestimate the cooling impact of some clouds.

Focus

The Aerosol Properties & Processes research program 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 use very detailed, small-scale models of new particle formation and ice nucleation in cirrus clouds. In addition, we collaborate with numerous modeling groups on how data on aerosols can constrain global and regional models of aerosols.

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.
