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.
