WebThe ionosphere can be divided into layers, D, E and F: D Region; The D region refers to the lowest layer. It is observed at altitudes ranging from 60 to 90 kilometers. The largest part of the HF absorption takes place in the D-layer, in particular frequencies lower than 10 MHz. WebThe different layers of ionosphere and ionospheric density variation are explained in this lecture.
