A researcher works on construction of a new experiment at the South Pole Station known as SuperDARN. SuperDARN stands for Super Dual Auroral Radar Network. The network consists of more than 30 low-power high-frequency radars around the world that look into Earth's upper atmosphere beginning at mid-latitudes and extending into the polar regions. The radars operate continuously and observe the motion of charged particles (plasma) in the ionosphere and other effects that provide scientists with information on Earth's space environment. The knowledge gained from this work provides insight into space weather hazards including radiation exposure for high-altitude travelers and disruptions to communication networks, navigation systems (GPS), and electrical power grids.
