Ionosphere experiment
Web6 mrt. 2015 · It is an advanced model of an “ionospheric heater.” (The ionosphere is the electrically-charged sphere surrounding Earth’s upper atmosphere. It ranges between 40 to 60 miles above the surface of the Earth.) Put simply, the apparatus for HAARP is a reversal of a radio telescope; antenna send out signals instead of receiving. The ionosphere is a shell of electrons and electrically charged atoms and molecules that surrounds the Earth, stretching from a height of about 50 km (30 mi) to more than 1,000 km (600 mi). It exists primarily due to ultraviolet radiation from the Sun. The lowest part of the Earth's atmosphere, … Meer weergeven The ionosphere is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, a region that includes the thermosphere and parts of the mesosphere and Meer weergeven An ionospheric model is a mathematical description of the ionosphere as a function of location, altitude, day of year, phase of the sunspot cycle and geomagnetic activity. … Meer weergeven X-rays: sudden ionospheric disturbances (SID) When the Sun is active, strong solar flares can occur that hit the sunlit side of Earth with hard X … Meer weergeven As early as 1839, the German mathematician and physicist Carl Friedrich Gauss postulated that an electrically conducting region of the atmosphere could account for observed variations of Earth's magnetic field.
