HAARP

Under the High Frequency Active Auroral Research Program (HAARP), the United States government created an ionospheric heater, so called because the excitation of electrons increases their temperature, and it is the most powerful ionospheric heater in the world. One of them is located on the military testing ground in Alaska and its full-scale tests are to begin in early 2003. The second one is in Greenland and the third one in Norway.
