Ionosphere at night
WebThe third mode is the one of the night effect. Ionospheric layers and sky wave Atom ionization consists in losing or capturing one of more electrons, and becoming electrically unbalanced. Natural ionization occurs in the ionosphere under the bombardment of solar ionizing rays which detach electrons from atoms. WebThese two layers combine at night. Above, the F layer is fully ionized. It is sometimes known as the photosphere or the H region. The ionosphere is not homogeneous and unchanging. It is in constant flux. Therefore, it's …
