WebThe ionosphere is also where the auroras occur when solar wind particles collide with oxygen and nitrogen atoms. The IRI transmits at frequencies between 2.7 and 10 MHz with a power of 3.6 megawatts. It transmits radio waves upward into the ionosphere, where they cause electrons to move in waves. Webthe auroral zone include an additional source term in equation (6) representing effects of multiple ionizations of the ionosphere by the precipitating energetic electrons [e.g., Sato, 1978; Watanabe et al., 1993; Pokhotelov et al., 2002]. That term requires some additional assumptions about electrons acceleration in the upward current channel ...
