Webionosphere with altitude. Typically, the collision frequency strongly exceeds the gyro frequency for both ions and electrons up to a height of about 70 km. Up to this altitude the parallel and Pedersen conductivities dominate. Above about 70 km the electrons start to gyrate and drift perpendicular to the electric field, while the Webthe ionosphere. In principle a similar discussion also applies to ionospheric electrons, in terms of the ratio of the electron- neutral collision frequency to the electron gyrofrequency. However, this ratio remains small throughout the whole region of the ionosphere where appreciable plasma densities are present (above -90 km).
