This $732,679 federal Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) aims to improve the understanding of atmospheric methane oxidation by hydroxyl and chlorine radicals. The project will involve fabricating a laboratory photochemical reactor to study the kinetic isotope effects of these reactions under a wide range of experimental conditions, including temperature, pressure, and reactant concentrations. The primary analytical techniques will be tunable infrared laser direct absorption spectroscopy, Fourier-transform infrared spectroscopy, and UV absorption spectroscopy to provide high-precision measurements of methane mole fraction and isotopic composition. This research is expected to substantially reduce uncertainties in annual global methane emissions from fossil fuel and microbial sources. The University of Rochester, a private research university, will be the sole performer of this 3-year project, which commenced on September 1, 2025.
