Web• Several layers have been identified and called D, E, Fl and F2 • Different layers form because: a) the solar spectrum ionises at various heights depending on the absorption characteristics. b) the recombination rate depends on the density, and there is more than one recombination process. c) the atmospheric composition changes Websince they are the only tool to diagnose the lower ionosphere. Lower part of the Earth’s ionosphere ranging 50 ∼ 90 km is known as the D-region of the ionosphere. Solar Lyman-α radiation at 121.8 nm and EUV radiation in 80 ∼ 111.5 nm are mainly responsible for forming the D-region through the ionizationofNO,N2,O2 duringdaytime.
