The objectives are to: 1)...
- 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...
- 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 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 $1,882,550 National Science Foundation project grant supports research into the evolution of secondary organic aerosol (SOA) formation processes in urban atmospheres. Funded under the Geosciences program (CFDA 47.050), the three-year award to the University of Colorado will investigate the key gas-phase precursors and sources contributing to SOA, and evolution of associated chemistry over the past decade. A six-week field campaign in the Los Angeles area in summer 2022 aims to compare...
- This $272,363 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research effort at Aerodyne Research Inc. to better understand the formation and yields of key secondary atmospheric species, such as ozone, formaldehyde, and secondary organic aerosol, resulting from the oxidation of non-methane volatile organic compounds. The research will involve model-informed chamber studies to carefully control and monitor the reactivity of...
- 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 three-year $570,934 National Science Foundation project grant supports research at the University of California, Irvine to study the effects of phase state on secondary organic aerosol partitioning and its impacts on atmospheric processes at regional and global scales. Specifically, the university will implement methods in the GEOS-Chem model to predict glass transition temperatures and viscosity of secondary organic aerosol. Researchers will derive equilibration timescales of...
- 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...
AGS-PRF: TRIPLE OXYGEN ISOTOPE INVESTIGATIONS OF ORGANIC AEROSOL OXIDATION -THIS POSTDOCTORAL RESEARCH FELLOWSHIP FOCUSES ON AN INVESTIGATION OF THE OXIDATION CHEMISTRY OF ORGANIC AEROSOL IN THE ATMOSPHERE AND HOW THIS CHEMISTRY CAN LEAD TO COMPOSITIONAL CHANGES IN THE AEROSOL THAT ALTER ITS OPTICAL PROPERTIES. THIS PROJECT WILL ELUCIDATE SOME OF THE MECHANISTIC DETAILS OF ORGANIC AEROSOL OXIDATION THAT HAVE BEEN PREVIOUSLY INACCESSIBLE. CHANGES IN AEROSOL OPTICAL PROPERTIES CAN RESULT IN CHANGES IN AEROSOL-RADIATION INTERACTIONS THAT INFLUENCE CLIMATE. THIS RESEARCH WILL ADDRESS THE FOLLOWING QUESTIONS: (1) WHAT ORGANIC AEROSOL (OA) OXIDATION PATHWAYS ARE THE MOST IMPORTANT CONTRIBUTORS TO CHANGES IN AEROSOL COMPOSITION IN URBAN AND RURAL ENVIRONMENTS? (2) DO THESE OXIDANT-SPECIFIC CONTRIBUTIONS VARY FOR DIFFERENT AEROSOL SOURCES OR WITH THE SEASONS? (3) HOW DO THE EXTENT AND PATHWAYS OF OA OXIDATION AFFECT ITS OPTICAL PROPERTIES? THE POSTDOCTORAL SCHOLAR HAS DEVELOPED AN INNOVATIVE METHODOLOGY FOR THE TRIPLE OXYGEN ISOTOPE MEASUREMENT OF ORGANIC MATTER THAT CAN BE USED TO DIFFERENTIATE AND QUANTIFY THE SPECIFIC OXIDANTS CONTRIBUTING TO ATMOSPHERIC OXIDATION PROCESSES. THE EXPERIMENTAL PLAN INCLUDES UTILIZING CARBON AND NITROGEN ISOTOPES TO DISTINGUISH OA SOURCES AND TRACK (PHOTO)CHEMICAL AGING AND CHARACTERIZING THE IMPACT OF DIFFERENT ATMOSPHERIC OXIDATION PATHWAYS ON OA LIGHT-ABSORBING PROPERTIES. THE PROJECT INCLUDES THE SUPPORT AND MENTORSHIP OF LOCAL HIGH SCHOOL STUDENTS AND SUMMER UNDERGRADUATE STUDENTS. THIS AWARD REFLECTS NSF'S STATUTORY MISSION AND HAS BEEN DEEMED WORTHY OF SUPPORT THROUGH EVALUATION USING THE FOUNDATION'S INTELLECTUAL MERIT AND BROADER IMPACTS REVIEW CRITERIA.- SUBAWARDS ARE NOT PLANNED FOR THIS AWARD.
