An investigation of the mid-latitude ionospheric D-region under twilight conditions in summer.
Abstract
In this paper variations of electron density of the ionospheric D-region are investigated for twilight conditions in summer at middle geographical latitudes. The used model includes λ, the negative ion to electron concentration ratio, as a basic parameter for photodetachment processes. The following ionization sources are considered: galactic cosmic rays, precipitating electrons, scattered Lyα- and Lyβ-radiation and directly incident Lyα-radiation.
