Project Grant 2501332
- The National Science Foundation (NSF) awarded a $797,203 Project Grant under its Geosciences program (CFDA 47.050) to the University of California Irvine (UC Irvine). The goal of this 3-year project, with an end date of January 2027, is to better understand how photochemical reactions in the solid or liquid phase of organic compounds affect the key properties of organic aerosol in the atmosphere. The research will focus on secondary organic aerosol (SOA) and/or biomass burning organic aerosol...

Researchers will derive equilibration timescales of...
- 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...
- This Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $214,924 to Aerodyne Research Inc. to develop a field-deployable Oxidation Flow Reactor and conduct associated laboratory and field studies. The Reactor will be used to better understand nighttime chemistry in the atmosphere, specifically the relative contributions of hydroxyl and nitrate radicals to the formation of oxidized...
- This National Science Foundation (NSF) Geosciences program (CFDA 47.050) project grant award of $213,206 to the University of California, Merced aims to provide new knowledge on the fate of peroxy radicals in the atmosphere. The 5-year project will conduct experiments at the NSF NCAR chamber facility to study the mechanisms and kinetics of peroxy radical reactions, particularly as regions transition from polluted to limited nitric oxide environments. The key objectives are to: 1) characterize...
- This $750,000 Project Grant was awarded on August 15, 2024 by the National Science Foundation (NSF) under the Mathematical and Physical Sciences Federal Grant Program (CFDA 47.049) to the Massachusetts Institute of Technology (MIT). The research team led by Professors Jesse Kroll and William Green will carry out experimental and computational studies to investigate the chemical reactions of organic peroxy (RO2) radicals in atmospheric droplets and particles. The goal is to gain a predictive,...
- The University of California, Los Angeles (UCLA) received a $500,000 Project Grant from the National Science Foundation's (NSF) Mathematical and Physical Sciences Program (CFDA 47.049) to investigate gas-phase reaction pathways of peroxy radicals (RO2), which are central intermediates in the oxidation of organic compounds in the Earth's atmosphere. The research, led by Professor Victoria Barber, aims to improve understanding of how isomerizations and self- or cross-reactions of peroxy radicals...
- 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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to quantitatively assess the influence of salt on the aqueous partitioning of water-soluble organic gases in the atmosphere. The $709,720 project, which runs from December 2024 to November 2027, will involve field and laboratory measurements, reanalysis of prior atmospheric chemistry data, and the development of parameterizations for implementation in chemical transport models....
This Project Grant award, in the amount of $274,143, was provided by the National Science Foundation (NSF) under the Mathematical and Physical Sciences program (CFDA 47.049). The award supports Professor Haofei Zhang at the University of California, Riverside in investigating the roles of gas-phase OH and HO2 radicals in the multiphase oxidation of organic aerosols (OA) under atmospherically relevant conditions. The research aims to provide critical knowledge for understanding aerosol aging chemistry, with potential implications for improving air quality and public health. The project will involve conducting laboratory experiments using a custom-designed flow reactor to study bimolecular and unimolecular peroxy radical autoxidation processes in the condensed phase, as well as the effects of inorganic species and aerosol liquid water on OA multiphase oxidation. The findings could contribute to broader societal goals of environmental protection and will also provide training opportunities for graduate and undergraduate students.
