Steven S. Brown is an Adjunct Professor of Chemistry at the University of Colorado Boulder and a Research Chemist at NOAA’s Chemical Sciences Laboratory (CSL). He leads NOAA’s Tropospheric Chemistry and Atmospheric Remote Sensing programs, focusing on atmospheric composition dynamics with applications in air quality and climate. His research emphasizes nitrogen oxides (NOx), nighttime chemical cycles, and the development of high-sensitivity optical instruments for trace gas and aerosol measurements.
Dr. Brown holds a Ph.D. from the University of Wisconsin-Madison (1996) and a B.A. from Dartmouth College (1989). He has conducted field campaigns such as FIREX-AQ, AEROMMA, and CalFiDE, studying biomass burning emissions, urban air quality, and regional pollution. His work has been recognized with prestigious awards including the NOAA Bronze Medal and Fellowships from the American Association for the Advancement of Science and the American Geophysical Union.
Key research themes include nocturnal radical chemistry (NO₃/N₂O₅), halogen cycling in the troposphere, and the impacts of biomass burning on ozone and aerosols. His laboratory develops instruments like cavity-enhanced spectroscopy systems for airborne and ground-based observations.
Recent work (2023–2025) highlights studies on urban ozone formation from volatile chemical products, wildfire plume dynamics, and stratospheric heterogeneous chemistry. Collaborations with agencies like CIRES and NASA emphasize interdisciplinary approaches to understanding atmospheric processes.
