Southern Hemisphere Auroral Radar Experiment

The Southern Hemisphere Auroral Radar Experiment ( SHARE) is a 1988 begun Antarctic research project on the observation of speed and irregularities in the electric fields of the ionosphere and magnetosphere, organized jointly by the University of Natal, Potchefstroom University, the British Antarctic Survey and the Johns Hopkins University is coordinated. The investigations are carried out in Antarctica to the South African SANAE IV station and, about 1000 km of which remote stations Halley (England) and Syowa (Japan).

For this purpose, a total of 16 antennae, each on a separate 12 m high tower, in use, which operate at a fixed frequency of 8-20 MHz. The operation corresponds to that of a conventional radar - every two minutes by passing a high-frequency radio signal through the antenna in the upper atmosphere.

The fields of the three research stations overlap so that a large part of the Antarctic continent can be covered. The project is also part of the international Super Dual Auroral Radar Network ( SuperDARN ) and provides valuable data for determining the solar energy fields that radiate to the earth ( " space weather ").
