Abstract

The ionosphere is so named because it is a region in the atmosphere 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 an electron is set free. What remains is a positive ion (a molecule that is “missing” an electron) and a free electron. Although ions give their name to the region, free electrons actually affect radio waves. The number of electrons starts to increase at an altitude of about 30 km, but the electron density isn’t sufficient to affect radio waves until about 60 km. We often think of the ionosphere as having a number of distinct layers.
