SuperDARN

SuperDARN (Super Dual Auroral Radar Network) is an international scientific system that uses high-frequency radio waves to study the Earth's upper atmosphere, particularly the ionosphere and magnetosphere. By bouncing signals off charged particles in these regions, it can detect patterns of plasma flow and disturbances caused by space weather and solar activity. This information helps scientists understand phenomena like auroras and how solar winds impact Earth's magnetic field, which can affect communication, navigation systems, and power grids. Essentially, SuperDARN provides real-time, large-scale insights into the dynamic space environment surrounding our planet.
