William H. Brune

William H. Brune is a Distinguished Professor of Meteorology in the Department of Meteorology and Atmospheric Science at the College of Earth and Mineral Sciences, Pennsylvania State University, holding a Ph.D. from Johns Hopkins University. His research program integrates atmospheric chemistry expertise across multiple scales, from Earth's surface to the stratosphere, with a focus on oxidation processes critical to air quality and climate.

His primary research interests include:

• Atmospheric photochemistry across vertical atmospheric profiles
• Aerosol particle formation, aging, and chemical transformation
• Uncertainty quantification and sensitivity analysis in atmospheric chemistry models
• Innovative measurement strategies for oxidation processes

Brune's work is distinguished by instrument development for direct radical measurements (OH/HO2), OH reactivity, potential aerosol mass, and ozone production rates. His Potential Aerosol Mass (PAM) chamber technology has been adopted by over a dozen international research groups for standardized aerosol studies. Analysis of his 2004-2018 publications reveals consistent investigation of oxidation chemistry in diverse environments—urban plumes, forested regions, and upper troposphere—with increasing emphasis on biogenic-anthropogenic interactions and cloud-mediated chemistry.

No specific scientific awards were detailed in source materials, though his Distinguished Professor title signifies institutional recognition. He actively mentors students through instrument development and major field campaigns like DC3 (Deep Convective Clouds and Chemistry), while leading a laboratory focused on advancing atmospheric measurement techniques for global environmental challenges.
