Focus

Our program area has two research directions: airborne field measurements of trace gases and aerosols, and laboratory measurements of atmospheric chemical processes.

Field Measurements

We design, develop, and deploy instruments aboard research aircraft for measurements of trace gases and particles. We interpret these observations to improve our understanding of atmospheric processes related to air quality, ozone depletion, and climate change.

Laboratory Studies

We characterize the atmospheric lifetimes and photochemical processing of trace species emitted into or formed in the atmosphere and their impact on ozone production, air quality, and climate. We develop instrumentation for the detection of key atmospheric species to improve our ability to study key atmospheric species in the laboratory and field.
