Radio Wave Propagation
As a society we have become dependent on satellite communications, but satellites fail with alarming frequency. Before the advent of satellites, long distance communications were carried out with high frequency (HF) radio transmissions. This lesson examines the factors that control long-distance radio communications, with an emphasis on refraction in the ionosphere, frequency selection, and the effects of solar radiation.

Radio Frequency Coordination (RFC)
The fifteenth World Meteorological Organization Congress (Geneva, May 2007), attended by 163 Member countries, confirmed serious concern at the continuous threat to radio frequency bands allocated for meteorological and related environmental systems expressed by the Fourteenth Congress and adopted Resolution 4 (Cg-XV) – Radio frequencies for meteorological and related environmental activities – in which WMO’s 188 Member states and territories are urged to make all efforts to do their utmost to ensure the availability and protection of suitable radio frequency bands required for meteorological ...
