This federal Project Grant award of $141,789, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research into the effects of ionospheric density irregularities on high-frequency (HF) radio wave propagation. The project, led by researchers at The Johns Hopkins University, aims to investigate how solar and geomagnetic activities influence ground-based HF communications, analyze small-scale density irregularities in the ionosphere, and evaluate how HF waves propagate through the irregular density profile. By utilizing satellite data, HF amateur radio communication datasets, and advanced finite element method simulations, the project seeks to enhance understanding of HF radio wave propagation through the ionosphere and improve ground-based HF communications, which have applications in international broadcasting, aircraft/military operations, and emergency situations. The award, which runs from November 1, 2024 to October 31, 2027, also provides opportunities for underrepresented communities in STEM fields and integrates research into a Ham radio science citizen investigation program.
