WebJonathan M. Blackledge, in Digital Image Processing, 2005. 7.6 Case Study: Imaging the Ionosphere. The ionosphere is a weakly ionised gas which exists between the Earth’s atmosphere and the magnetosphere. At long wavelengths the ionosphere behaves like a layered dielectric, and its ability to reflect radio waves is well known. WebIonosphere altitude. The ionosphere is the upper layer of the Earth’s atmosphere. The atmosphere is partly ionised by solar UV-light, and such ionisation can persist at high altitude: the ionosphere starts at about 80 km altitude and reaches up to more than 1000 km..
