This Project Grant award from the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) will fund research to quantitatively assess the influence of salt on the aqueous partitioning of water-soluble organic gases in the atmosphere. The $419,614 project, awarded to the University of Maryland Baltimore County (UMBC), has the following key objectives: (1) measure the effects of atmospherically relevant inorganic salt mixtures on partitioning of ambient water-soluble organic gases; (2)...
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 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 from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $202,000 in funding to support a postdoctoral research fellowship focused on investigating the oxidation chemistry of organic aerosols in the atmosphere. The research aims to elucidate the mechanistic details of how organic aerosol oxidation can lead to changes in aerosol composition and optical properties, which can influence climate. The project will utilize an innovative methodology...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $202,000 to support observational and modeling research aimed at developing a unified source function for giant sea salt aerosols (GSSA). The research, conducted over a 2-year period from June 2025 to May 2027, will use specialized instrumentation to measure GSSA during research cruises from Hawaii. These observational data will be combined with large eddy simulation modeling to identify...
This $616,131 National Science Foundation project grant will fund the development of observation-based metrics to evaluate global atmospheric chemistry models at the University of California, Irvine through January 2025. As part of its Geosciences program, which supports basic research in atmospheric, earth, and ocean sciences, the NSF aims to strengthen the scientific enterprise's understanding of the integrated Earth system. Under this award, the university will design, test, and document a...
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 National Science Foundation (NSF) Geosciences program Project Grant award to the University of California, Irvine (UC Irvine) provides $772,000 over a 3-year period from February 2024 to January 2027. The award supports research to study secondary organic particle oxidation mechanisms using novel mass spectrometry techniques, including Matrix Assisted Ionization Mass Spectrometry (MAI-MS) and Easy Ambient Sonic-Spray Ionization Mass Spectrometry (EASI-MS). The objectives are to: 1)...
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 National Science Foundation project grant of $291,231 supports collaborative research on coastal cloud chemistry during the Eastern Pacific Cloud Aerosol Precipitation Experiment campaign. Funded under the Geosciences program (CFDA 47.050), the award will leverage recent instrumentation developments to augment the Department of Energy's campaign conducted in La Jolla, California from February 2023 to January 2024. Specifically, the University of California, Los Angeles will utilize...
