The SuperDARN now consists of 32 Radars operating on Frequencies between 8 MHz and 20 MHz and looking into the Polar Regions of the Earth. These Radars can measure the Position and Velocity of Plasma Irregularities in the Earth's Ionosphere, the highest Layer of the Earth's Atmosphere. The Movements of these Irregularities respond to Energy coupled into the Auroral Regions from the Solar Wind and the Magnetosphere. Therefore, SuperDARN Data provides Scientists with Information regarding the Earth's Interaction with the Space Environment.",
