Brune studies the atmosphere’s oxidation chemistry by making measurements in field campaigns and then modeling the measurements with photochemical box models. These studies address fundamental questions of air quality near Earth’s surface, of atmospheric effects of global pollution in the middle and upper troposphere, and of ozone destruction in the stratosphere. He, his research associates, and his students have developed instruments to measure atmospheric hydroxyl and hydroperoxyl radicals, OH reactivity (the inverse of the OH lifetime), potential aerosol mass, and the ozone production rate. Their Potential Aerosol Mass chambers are used by more than a dozen research groups for laboratory and field studies of particle formation and aging. He and his colleagues also assess atmospheric chemistry model uncertainty and the sensitivity of model outputs to model inputs. This research is focused on improving the understanding of atmospheric oxidation processes.
