The award is made under the Geosciences program (CFDA 47.050), which aims to expand understanding of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. Specifically, the University of Southern California project will develop and assess...
The National Science Foundation (NSF) awarded a $259,132 Project Grant to Carnegie Mellon University under the Mathematical and Physical Sciences Program (CFDA 47.049) to investigate peroxy radicals, which are highly reactive organic molecules that play a critical role in atmospheric and combustion chemistry. The project aims to develop a new and improved method for measuring these important chemical species using advanced mass spectrometry techniques. If successful, this work will provide...
This Project Grant award, funded by the National Science Foundation's (NSF) Mathematical and Physical Sciences Program (CFDA 47.049), supports a research project led by Professor James Smith of the University of California, Irvine. The $450,000 award, effective June 1, 2025 through May 31, 2028, will investigate the growth mechanisms of atmospheric aerosol nanoparticles, focusing on the interactions between organic compounds, inorganic acids, and bases. The project aims to identify the major...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $100,000 over 2 years to investigate the oxidation chemistry of organic aerosols in the atmosphere and its impact on their optical properties. The research will utilize innovative triple oxygen isotope measurements to elucidate the specific oxidation pathways that contribute to changes in aerosol composition, with the goal of understanding how these compositional changes affect...
This three-year, $749,453 National Science Foundation project grant funds research at the California Institute of Technology into the atmospheric oxidation of volatile chemical products and their impact on air quality. Led by Drs. Paul Wennberg, Brian Stoltz, and John Crounse, the research team will study the chemical reactions of oxygenated hydrocarbons as they degrade in the atmosphere. A major focus is whether radical autoxidation pathways produce highly oxygenated compounds that contribute...
This National Science Foundation project grant award of $816,275 will fund research at the University of California, Davis from July 2022 through June 2025 to improve understanding of how photo-oxidants form and influence the chemistry of atmospheric particles under the Geosciences program (CFDA 47.050). Specifically, the award will support measuring photo-oxidant concentrations and reaction kinetics in aerosol liquid water extracts from particles collected in Davis, California. It will also...
