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...
This $191,857 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research to determine the role of volcanic ash particles and hydrometeor concentrations in lightning generation. Over a three-year period, the University of Alabama will analyze earth observations, conduct laboratory measurements, and run model simulations to track the size and abundance of these particles following eruptions. The university will synthesize data from multiple...
This Project Grant award of $200,000 from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support research by the Florida Institute of Technology (Florida TECH) to study the relationship between high-energy radiation from thunderstorms, known as Terrestrial Gamma-Ray Flashes (TGFs), and their associated radio signals. The research aims to address key scientific questions about the mechanisms behind TGF formation and their connection to lightning. This project...
The National Science Foundation awarded a $139,000 project grant to Colorado State University's Sponsored Programs division under the Geosciences program (CFDA 47.050) from February 1, 2023 to July 31, 2025. The university will quantify major components of the global electric circuit through data mining of electric field and radar observations from ground-based, airborne and satellite platforms. Specifically, CSU will examine electric field measurements above clouds from past field campaigns...
