This $120,000 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research into gigantic jets (GJs), large electrical discharges that couple the troposphere and ionosphere. Duke University will construct climatologies of GJs by developing a machine learning classifier to detect them by the thousands using data from the Geostationary Lightning Mapper. Validation will incorporate ground-based radio networks to filter non-lightning events and determine...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $659,177 Project Grant to the Georgia Tech Applied Research Corporation to investigate gigantic jets (GJs), their ionospheric effects, and how they couple the troposphere and ionosphere. Under the Geosciences program (CFDA 47.050), the award seeks to advance scientific understanding of how cloud-to-ionosphere electrical discharges known as GJs transfer charge between the lower atmosphere and ionosphere. The...
This five-year, $1.286 million Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences will fund research into stormtime magnetosphere-ionosphere coupling and the enhancement of the dawnside auroral electrojet. Under the Geosciences program (CFDA 47.050), which supports basic research in atmospheric, earth, and ocean sciences to expand understanding of the integrated Earth system, the Johns Hopkins University will investigate the ionospheric current and...
This $212,120 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) funds research into the impacts of atmospheric waves and geomagnetic disturbances on space weather conditions. Led by the Massachusetts Institute of Technology in collaboration with Clemson University, Embry-Riddle Aeronautical University, New Jersey Institute of Technology, and Virginia Polytechnic Institute and State University from May 1, 2022 to April 30, 2025, the research will advance...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $810,271 Project Grant to the University of California Santa Cruz under the Geosciences program (CFDA 47.050) from February 1, 2023 to January 31, 2026. The award will support research to better understand the conditions under which terrestrial gamma-ray flashes (TGFs) are produced during lightning storms. Radiation sensors will be deployed globally, including at high- and low-altitude sites with strong...
This $2,184,050 three-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports lightning and thunderstorm studies at the New Mexico Institute of Mining and Technology in Socorro, New Mexico. The award funds research to further understanding of lightning production mechanisms and terrestrial gamma ray flashes. Studies utilize multiple lightning detection systems including lightning mapping arrays and dual broadband interferometers to obtain...
This $292,793 Project Grant was awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) to the Regents of the University of Michigan to study the interaction of lightning-generated whistlers with radiation belt electrons. The primary objective is to develop stochastically parameterized diffusion models to more accurately capture the rate of pitch angle scattering and precipitation of these electrons into the Earth's atmosphere. This will improve the ability to predict...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award in the amount of $441,951.00, with a performance period from January 1, 2025 to December 31, 2027, will support an experimental study on the role of secondary electron emission in atmospheric electricity, with a focus on electric discharges and their initiation in planetary atmospheres. The key objectives are to: (a) understand how secondary electron emission influences the ignition of electric...
This $200,000 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research by the Florida Institute of Technology Inc. (Florida TECH) to investigate the relationship between terrestrial gamma-ray flashes (TGFs) and lightning. The project will merge large datasets from satellite and ground-based sensors to address scientific questions about the mechanisms behind TGF formation and their connection to lightning, with the goal of improving...
The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $407,336 Project Grant to the Regents of the University of Colorado, a U.S. state government entity and institution of higher learning, under the NSF's Geosciences program (CFDA 47.050). The funding will support data-driven modeling to study the day-to-day and longitudinal variability of the equatorial electrojet, a critical electrodynamic feature of the low- and mid-latitude ionosphere. Key...
