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 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...
The National Science Foundation awarded a $533,566 Project Grant to the University of Miami under the Geosciences program (CFDA 47.050) to support the acquisition of an Aerosol Characterization System. The System will be operated at the University's Ragged Point site in Barbados and is expected to open new research avenues related to the transport of African dust to the Americas, the impact of ocean-derived organic aerosols in the marine boundary layer, wildfire smoke, and cloud and radiation...
Aerodyne Research Inc. was awarded a $224,940 Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences to conduct collaborative research studying the role of organic peroxy radicals (RO2) chemistry on the evolution of atmospheric organic carbon. The three-year award, issued on December 1, 2021 under the Geosciences program (CFDA 47.050), will support basic research at Aerodyne's facility in Billerica, MA through November 30, 2024. The Geosciences program...
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 National Science Foundation project grant of $582,172 will fund the development of optical classification models for ambient aerosols using machine learning. Awarded under the Geosciences program of the Division of Atmospheric and Geospace Sciences, this three-year project beginning March 2022 aims to build tools that can differentiate aerosol types based on measured optical properties without prior assumptions. The University of Georgia Research Foundation will receive funding to...
This $1.5 million National Science Foundation project grant supports research into secondary marine aerosol precursors and their links to aerosol growth during Arctic sea ice melt onset. Funded under the Geosciences program (CFDA 47.050), the goal is to advance understanding of secondary marine aerosol formation in the atmosphere and its impact on cloud properties and climate. Colorado State University will conduct measurements of volatile organic compounds and reduced sulfur compounds aboard...
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...
