Research Programs

CSL researchers collaborate extensively within and without the laboratory, blurring the lines between the research programs described below. Each program area makes important contributions to CSL's primary research themes of air quality, climate, and the stratosphere. This strong overlap of interests and productivity helps create the vibrant, robust atmospheric research environment for which the Chemical Sciences Laboratory is widely known.


Aerosol Properties & Processes

Dr. Daniel M. Murphy

This research program studies processes important to climate, air quality, and precipitation. We measure the physical, chemical, and optical properties of aerosol particles in the field and laboratory to better understand the sources, sinks, and radiative properties of these particles. We utilize advanced data analysis and models to understand the implications of these measurements for the atmosphere. Learn More


Atmospheric Composition & Chemical Processes

Dr. Joshua (Shuka) Schwarz

Through airborne field measurements, this research program targets trace gases, aerosols and atmospheric chemical processes affecting air quality, ozone layer depletion, and climate. We design, develop, and deploy instruments to measure atmospheric trace gases and particles, and interpret observations to better understand atmospheric processes. Learn More


Atmospheric Remote Sensing

Dr. W. Alan Brewer

This research program uses land, ship, and aircraft-based optical systems to study processes of importance to air quality, climate, aviation, weather forecasting, wind energy, and marine ecosystems. Our capabilities and interests include the development and deployment of state-of-the art lidar and spectroscopic instrumentation, and the interpretation of data obtained with these systems.

Chemical Processes & Instrument Development

Dr. James B. Burkholder

With precision laboratory work, this research program targets trace gases, aerosols and atmospheric chemical processes affecting air quality, ozone layer depletion, and climate. We characterize the lifetimes and photochemical processing of trace species, and evaluate their impact. Learn More


Chemistry & Climate Processes

Dr. Karen H. Rosenlof

This research program provides integrated analysis and modeling that addresses chemistry and climate processes spanning the troposphere and stratosphere. We advance the scientific building blocks that underlie science and policy, and we provide scientific leadership to improve understanding and directly assist public policy. Our researchers collaborate widely, with colleagues at NOAA and academia to those in international research organizations. Learn More


Clouds, Aerosol, & Climate

Dr. Graham Feingold

This research program studies clouds, their interaction with aerosol particles, their radiative properties, and their ability to produce precipitation. Our researchers use diverse, innovative modeling techniques as well as observations to understand the physical and radiative properties of clouds. Learn More


Regional Chemical Modeling

Dr. Gregory J. Frost

This research program conducts research to improve forecasts of regional air quality, including particulate matter and ozone, and to improve understanding of the free tropospheric ozone budget. We use the WRF-Chem chemical transport model to develop and evaluate state-of-the-art innovative ways of describing and forecasting the emission, transport, and chemical evolution of pollutants in the atmosphere. Learn More


Tropospheric Chemistry

Dr. Steven S. Brown

Researchers in this program improve understanding of the emissions and atmospheric processes that underlie air quality and the influence that these processes have on climate. We develop and field deploy state-of-the-art instruments capable of measuring important atmospheric gas and aerosol species from ultra-trace levels to the extremely high concentrations found at emission sources. We collaborate widely to draw on diverse techniques, from laboratory to modeling studies. Learn More
