Abstract

The ionosphere is a region of the space near-Earth (geospace) environment characterized by free ions and electrons produced, in most part, by solar photoionization. Studies of the ionosphere are motivated by a need to better understand (a) the role of fundamental physical processes responsible for ionospheric variability caused by different drivers, (b) impacts of ionospheric variability on radio signals used by…
