Project Grant 2225122
- This three-year, $969,646 National Science Foundation Project Grant in the Geosciences program (CFDA 47.050) supports research at the University of Texas at Dallas to study nonlinear interactions between energetic electrons and oblique whistler-mode chorus waves in Earth's outer radiation belt. The investigators will develop numerical models of oblique chorus wave packets and electron phase space density evolution. They will quantitatively compare model results with in-situ measurements from...
- 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 National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $109,432 to Atmospheric & Space Technology Research Associates LLC (doing business as Orion Space Solutions) to characterize whistler-mode wave properties in the plasmasphere-plasmatrough transition regions. The research aims to improve understanding of the combined effects of chorus and hiss waves on the Earth's radiation belt environment, which can impact spacecraft and aviation....
- This $378,011 Project Grant from the National Science Foundation's (NSF) Division of Atmospheric and Geospace Sciences will fund controlled whistler mode wave injection experiments at the High Altitude Auroral Research Program (HAARP) facility in Alaska. The project aims to understand how certain radio waves launched into space can be amplified by energetic particles, which is critical for improving models of space weather phenomena and radiation belt dynamics. The award supports graduate and...
- 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 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 University of California, Los Angeles (UCLA) was awarded a $534,210 Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences. The grant supports research titled "Time Domain Structures Driven by Whistler and Kinetic Alfven Waves in a Laboratory Plasma" from July 15, 2021 to June 30, 2024. Under this award, UCLA researchers will investigate time-dependent structures in plasma driven by whistler and kinetic Alfven waves. This work furthers...
- The National Science Foundation (NSF) awarded a $404,682 Project Grant under its Geosciences program (CFDA 47.050) to the University of Texas at Dallas (UTD). The grant, effective from September 1, 2025 to August 31, 2028, aims to investigate a newly reported wave mode, known as Electron Cyclotron Harmonic (ECH) waves, that interact with energetic electrons in the Earth's magnetosphere. The project will explore the excitation mechanism, favored magnetospheric conditions, and effects of these ECH...
- The National Science Foundation (NSF) Geosciences Program (CFDA 47.050) awarded a $521,853 Project Grant to The Regents of the University of Colorado (CU) on June 1, 2025. The 5-year grant, titled "The Evolution of Magnetospheric Plasma Waves in Response to Solar Driving," will focus on studying the complex dynamics of plasma waves in the Earth's magnetosphere and their impacts on phenomena such as the Van Allen radiation belts and atmospheric chemistry. The project will leverage...
- The National Science Foundation (NSF) awarded a $294,241 Project Grant under the Geosciences program (CFDA 47.050) to The Regents of the University of Colorado, doing business as the University of Colorado. The grant, titled "COLLABORATIVE RESEARCH: GEM--DETERMINING THE GLOBAL IMPACT OF NONLINEAR WAVE-PARTICLE INTERACTIONS IN THE RADIATION BELTS," aims to study the effects of large-amplitude waves on the Earth's radiation belts using theory, modeling, and data analysis. The research...
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 packets and electron phase space density evolution to in-situ measurements from NASA's Van Allen Probes. The goal is to address knowledge gaps regarding how distinct electron harmonic resonances shape the outer radiation belt during intense chorus wave events. Findings may provide direct observational evidence of nonlinear Landau resonance. In addition to advancing fundamental plasma physics understanding, results will be incorporated into public outreach and university coursework to support early-career scientists and graduate students.
