Gombosi et al.) Current magnetopause position WebThe Ionosphere The ionosphere is so named because it is a region in the atmo-sphere where ions exist. In most areas of the atmosphere molecules are in a combined state and remain electrically neutral. In the ionosphere, however, solar radiation (mainly ultraviolet light) is so intense that when it strikes gas molecules they split—ionize—and

WebThe ionosphere is an atmospheric layer located at an altitude of about 50 kilometers and 500 kilometers. It has an extremely low density and is traversed by strong radiation as ultraviolet light, which in turn is highly ionized. This ionization causes the electronic bonds of the atoms to break down producing ions of different charges.
