Project Grant 83540001

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...

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 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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $268,460 to The Research Foundation for the State University of New York (RF SUNY) to develop an improved method for estimating nitrogen oxide (NOx) emissions using new-generation satellite observations. The key objectives are to: 1) Assess the accuracy and improve the theoretical understanding of the observation-based framework for estimating emissions using atmospheric model...

This National Science Foundation project grant award of $334,376 will fund the development of a new field-deployable Oxidation Flow Reactor tool and its use in laboratory and field studies to advance understanding of nighttime nitrogen chemistry in the atmosphere. Specifically, the collaborators will build an Oxidation Flow Reactor to provide new insights into nitrate radical-initiated atmospheric oxidative aging processes and the relative contributions of hydroxyl and nitrate radicals to the...

This $250,766 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a 5-year research project by the University of South Carolina to improve predictions of atmospheric nitrate formation across the United States. The project aims to quantify nitrogen oxide precursor emissions and oxidation pathways using stable isotope analyses and 3D atmospheric chemistry modeling. This research will provide insights into the spatial and temporal patterns of...

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 $480,588 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a 3-year investigation by the University of California, Irvine (UC Irvine) to assess the emission rates and composition of biogenic volatile organic compounds (BVOCs) from urban trees, as well as their efficiency in capturing airborne particles. The study aims to determine which tree species are best suited to help reduce air pollution in urban areas. Key activities include...

This $300,000 EAGER (Early-concept Grants for Exploratory Research) project, awarded by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050), aims to examine whether chemical reactions can alter the composition of land-derived organic carbon in a way that makes it appear similar to marine organic carbon. The research team from Old Dominion University Research Foundation will conduct experiments to monitor the reaction rates and compositional changes of land-derived...

This $313,664 Project Grant award from the U.S. Environmental Protection Agency (EPA) Region 4 under the Surveys, Studies, Research, Investigations, Demonstrations, and Special Purpose Activities Relating to the Clean Air Act (CFDA 66.034) program will provide financial assistance to the North Carolina Department of Environmental Quality (NCDEQ) to implement its program to address air quality concerns in North Carolina. The key activities to be funded include upgrading old equipment in...
