The National Science Foundation Division of Atmospheric and Geospace Sciences awarded The University of Iowa $143,232 on August 1, 2026, under the Geosciences program (CFDA 47.050) to measure low-frequency whistler-mode hiss waves in Earth's magnetosphere and quantify their role in energetic particle dynamics. The project implements an improved methodology to detect and characterize low-frequency hiss wave properties—specifically wave amplitude and frequency distributions—that were previously obscured by instrumental noise limitations in standard sensor systems. By circumventing these noise constraints, the research will enable observation of a significantly larger fraction of naturally occurring hiss waves, filling a known measurement gap. The resulting wave database and improved understanding of how hiss waves influence electron dynamics in the inner magnetosphere will enhance the accuracy of simulations predicting high-energy particle behavior near Earth and associated hazards to robotic and crewed spacecraft. Work is performed in Iowa City, Iowa, with a period of performance from August 1, 2026, through July 31, 2029.
