Webconducting atmosphere below. One of the important generators of the ionospheric current is the ionospheric wind dynamo, which operates as upper-atmospheric winds move the elec-trically conducting medium through the Earth’s magnetic ﬁeld, creating an electromotive force that drives currents and causes electric polarization ﬁelds to develop. Webtion also strongly affects ionospheric velocities, as a contin-ual accelerating force moving ions back into corotation with the planet. As such, the measurement of ion ﬂows within the ionosphere, moving against this background neutral atmo-sphere, provides a direct measure of the electric currents that cross the ionosphere. 2.
