The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $872,179 Project Grant to Trustees of Indiana University, doing business as Indiana University, for the "Seasonal Measurements of Hydrogen Oxide Radical (HOx) Chemistry in Forests" project. The 3-year grant, running from September 1, 2023 to August 31, 2026, will fund measurements of hydroxyl radical and peroxy radical concentrations in different forest environments, including Indiana...
The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $199,997 Project Grant to The Research Foundation For The State University Of New York, doing business as Suny ESF, under the NSF Geosciences federal grant program (CFDA 47.050) with a period of performance from July 1, 2023 to June 30, 2024. The grant is supporting a RAPID project to characterize the sources and chemistry of nitrogen oxides, nitrous acid, and particulate nitrate during the AEROMMA...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $250,766 to the University of South Carolina to improve the prediction of atmospheric nitrate levels across the United States. The project seeks to quantify nitrate formation pathways and characterize the variability of nitrate precursor emissions by integrating stable isotope analyses and 3-D chemistry transport modeling. This will enhance model predictions of nitrate and enable more...
This $649,388 Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences, under the Geosciences program (CFDA 47.050), will fund research exploring the impact of future land use change on global air quality and nutrient deposition. Specifically, the awardee, the Massachusetts Institute of Technology, will couple land use output from the Community Land Model simulations, driven by Shared Socioeconomic Pathways scenarios, to the GEOS-Chem global chemical...
The National Science Foundation's Geosciences Program (CFDA 47.050) awarded a $675,323 Project Grant to the University of California Irvine (UC Irvine) to study the role of urban and agricultural landscapes in biogenic volatile organic compound (BVOC) emissions and their impact on atmospheric ozone and aerosols. The project combines field and laboratory measurements with numerical modeling to quantify BVOC emissions from managed landscapes and their contribution to air pollution and...
This $582,005 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research by The Trustees of Princeton University to investigate nitrous oxide (N2O) consumption in the surface ocean. The research aims to determine the factors that control or stimulate N2O reduction in surface waters and characterize the microbes responsible for the process. Specifically, the investigators will perform 15N tracer incubations to measure the rate of N2O reduction...
This $163,674 National Science Foundation (NSF) Geosciences Program (CFDA 47.050) project grant award to the University of Southern California (USC) is focused on applying machine learning tools to improve the predictability of atmospheric chemistry and better understand the influence of the plant biosphere on atmospheric composition. The 5-year project aims to (1) quantify uncertainties in the impact of the plant biosphere on atmospheric chemistry, and (2) investigate how canopy-scale processes...
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...
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 Environmental Biology, under the Biological Sciences program (CFDA 47.074), provides $149,643 to San Diego State University Research Foundation from August 1, 2022 to July 31, 2025. The funding will support research to better quantify nitrous oxide (N2O) emissions in the North Slope of Alaska. Specifically, the grantee will measure N2O fluxes using chambers across vegetated and unvegetated areas in the coastal plain to constrain...
