The National Science Foundation (NSF) awarded a $210,153 Project Grant under the Geosciences Program (CFDA 47.050) to Embry-Riddle Aeronautical University to study the impact of solar eclipses on the ionosphere. The research seeks to quantify eclipse-driven changes in the ionosphere's electron density and identify key controlling factors, including reduced solar flux, thermospheric winds, and photoelectron transport. The project will leverage ground-based observations from the SuperDARN, Millstone Hill Incoherent Scatter Radar, and HamSCI HF facilities to investigate these phenomena. This work is intended to deepen the understanding of chemical and dynamical processes in the ionosphere-thermosphere system, with potential benefits for improving communication reliability, enhancing space weather predictions, and supporting STEM education and diversity. The award period runs from October 1, 2024, to March 31, 2027.
