Abstract

The term “ionosphere” for defining the ionized shells encircling Earth was introduced by V. Watt in 1929. The hypothesis that a conducting region should exist in the upper atmosphere was first advanced at the end of the nineteenth century first by B. Stewart and then by A. Schuster [Schuster, 1889] to explain diurnal variations of the geomagnetic field. However, this hypothesis became widespread only after Heaviside and Kennely explained in 1902 the propagation of radio waves over large distances. The existence of ionized regions in the upper atmosphere was directly proved in the 1920s. Of greatest importance was the invention of the pulse ionospheric station by G. Breit and M. Tuve [Breit and Tuve, 1926], who were the first to carry out radio probing of the ionosphere. In Russia, the first results in this field were obtained by M.V. Shuleykin [Shuleykin, 1923] who inferred from studying the operation of broadcasting stations that a radio wave exists that comes from above to Earth’s surface. He calculated the reflection height as 260 km.
