This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $345,680 in funding to The University of Iowa to characterize whistler-mode wave properties in the plasmasphere-plasmatrough transition regions. The project aims to investigate cases where the plasmapause density gradient is not sharp, in order to determine the properties of chorus and hiss waves in these transition regions. This will improve understanding of radiation belt dynamics...
The National Science Foundation (NSF) awarded a $515,885 Project Grant under the Geosciences Program (CFDA 47.050) to The Regents of the University of Colorado, doing business as the University of Colorado's Office of Contracts and Grants Division. The grant will support a 3-year research project to investigate the inward transport and energy-dependent penetration of energetic electrons (10s of keV to multi-MeV) from the Earth's outer radiation belt into the inner radiation belt. The research...
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...
This Project Grant award, with a funding amount of $294,241, was made by the National Science Foundation under its Geosciences Program (CFDA 47.050) to The Regents of the University of Colorado, conducting research on the global impact of nonlinear wave-particle interactions in the Earth's radiation belts. The research aims to quantify how large amplitude waves in the radiation belts can nonlinearly accelerate particles to high energies, potentially impacting the overall space environment....
This National Science Foundation Project Grant of $250,059 supports research at the University of California, Los Angeles from April 1, 2022 to March 31, 2024. The research aims to advance understanding and prediction of the Van Allen radiation belts through a novel combination of machine learning and data assimilation methods. Specifically, the Principal Investigator will use the Versatile Electron Radiation Belt model and data assimilation to discover generalized Fokker-Planck equations...
The Regents of the University of Colorado received a $432,033 Project Grant award from the National Science Foundation Division of Atmospheric and Geospace Sciences under the Geosciences federal grant program (CFDA 47.050). The grant will fund research from June 1, 2023 through May 31, 2026 to quantify the contribution of off-equatorial ultra-low frequency waves on radial diffusion in Earth's radiation belts. Specifically, the University will use satellite data from THEMIS, Van Allen Probes,...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $292,793 to the Regents of the University of Michigan will support research to improve the modeling and prediction of radiation belt electron dynamics, which can impact satellite operations and upper atmospheric processes. The primary objective is to study the interaction of lightning-generated whistlers with radiation belt electrons using stochastic parameterization methods from the weather and...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $260,221 to the New Jersey Institute of Technology (NJIT) from August 1, 2024 to July 31, 2027 to conduct collaborative research on determining the global impact of nonlinear wave-particle interactions in the Earth's radiation belts. The research aims to model the nonlinear wave-particle interaction in a global-scale radiation belt model to understand if these large-amplitude waves can...
