TRIDENT: Advancing ionospheric disturbance detection with next-gen HF sounders

Ian Collett, Ionospheric Scientist Understanding Earth’s ionosphere and how it responds to natural and human-induced phenomena has become increasingly critical in today’s interconnected world. Among the most significant phenomena are traveling ionospheric disturbances (TIDs). Gravity waves triggered by earthquakes, thunderstorms and rocket launches contribute to these disturbances. As they ripple through the ionosphere with varying intensity, they wreak havoc on communications...
