Layers of ionosphere
WebThe ionosphere is formed primarily when the most energetic component of the solar spectrum – the X-rays and extreme ultraviolet (EUV) light – impact the illuminated side of the Earth. These high-energy photons strike the daytime side of the Earth, ionizing the upper atmosphere and losing energy in the process. WebChapman Layer Model Chapman showed that the electron density of the resulting ionized layer can be expressed as: 0 Ø D L 0 à Ô ë A. 5 ? í ? Ø 7 å where V L Û ? Û Ø Ì ã Á, and *= scale height This provides a simple analytical expression to represent a layer in the ionosphere; used in models and data comparisons
