The research direction of our program area is laboratory measurements of atmospheric chemical processes.

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 these key atmospheric species in the laboratory and field.


We collaborate with other research groups to study and quantify chemical processes and develop instrumentation and the methods for measuring atmospheric trace species.
