Ionosphere measurement
WebThe ionosphere (/ a ɪ ˈ ɒ n ə ˌ s f ɪər /) ... Edward V. Appleton was awarded a Nobel Prize in 1947 for his confirmation in 1927 of the existence of the ionosphere. Lloyd Berkner first measured the height and density of the ionosphere. This permitted the first complete theory of short-wave radio propagation. WebThe uppermost part of the ionosphere, the F region, starts about 150 km (93 miles) and extends far upward, sometimes as high as 500 km (311 miles) above the surface of our home planet. The regions of the ionosphere are not considered separate layers, such as the more familiar troposphere and stratosphere.
