This $590,898 National Science Foundation award under the Geosciences program (CFDA 47.050) will fund research into modeling chorus wave generation using particle-in-cell simulations. Led by New Mexico Consortium, the project aims to study chorus waves—commonly observed plasma waves in Earth's inner magnetosphere—through large-scale first-principles simulations. The simulations will use realistic magnetic field topology and plasma parameters from observations to test existing theories of...
This $292,793 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to improve modeling and prediction of radiation belt electron dynamics driven by lightning-generated whistler waves. The primary objective is to develop stochastic parameterization methods to better capture the variability in the wave-particle interactions that govern radiation belt electron precipitation into the Earth's atmosphere. This research will help...
This National Science Foundation (NSF) Geosciences program Project Grant awarded to Auburn University totals $149,131 and runs from February 1, 2024 to January 31, 2029. The grant focuses on understanding the dynamics of energetic electron "fast, deep injections" into the Earth's inner radiation belt, which can impact spacecraft operations. Key objectives include: 1) investigating the characteristics of 100s of keV electron injections and their relation to solar wind/geomagnetic...
The National Science Foundation (NSF) awarded a $106,909 Project Grant under the Geosciences Program (CFDA 47.050) to Augsburg University in Minneapolis, Minnesota. The funding supports a collaborative research project to investigate the propagation and dissipation of electromagnetic ion cyclotron (EMIC) waves in the Earth's magnetosphere and ionosphere. The research team will employ advanced simulation models and analyze observations from multiple satellites and ground-based observatories to...
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 $449,990 Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will fund collaborative research at the University of Michigan to investigate the dynamics of fast plasma flows within the Earth's nightside magnetosphere and their effects on the upper atmosphere. The research aims to deepen understanding of the magnetosphere-ionosphere-thermosphere coupling processes using a combination of simulation models and multi-instrument observational data. Key...
This $688,588 National Science Foundation project grant supports research at Boston University to advance understanding of solar wind dynamics and their effects. Under the Geosciences program (CFDA 47.050), the funding will be used to investigate how positive and negative changes in solar wind dynamic pressure impact waves, energetic particles, and precipitation in Earth's magnetosphere and ionosphere. Researchers will analyze satellite data from missions such as THEMIS, Van Allen Probes, MMS,...
This three-year, $223,760 National Science Foundation project grant funds research at the University of California, Los Angeles to study energetic electron interactions with oblique whistler-mode chorus waves. Under the NSF's Geosciences program (CFDA 47.050), which supports basic research to enhance understanding of the integrated Earth system, this award will quantitatively analyze wave-particle dynamics using numerical models. Researchers will compare simulations of oblique chorus wave...
This National Science Foundation Project Grant award of $396,722 provides funding from October 1, 2022 through September 30, 2026 to Auburn University for research titled "Collaborative Research: GEM--Impact of Solar Wind Dynamic Pressure Enhancement on the Cusp and Polar Cap Ion Source." The award supports the Geosciences program (CFDA 47.050) goal of expanding fundamental knowledge of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences....
This $196,137 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to characterize the physics of interactions that drive the outflow of energized ions from the high-latitude ionosphere into near-Earth space. The goal is to develop an empirically derived physical model for ion heating in broadband electromagnetic waves, using observations from the FAST spacecraft. The research will advance the understanding of magnetosphere-ionosphere...
