Abstract
DR. LYON concludes that, at the magnetic equator, the vertical distribution of electron density N takes the form N ∝ e−2z above the F2 peak, the height z being measured in units of the scale height of the ionizable gas. This is in contrast to the situation at high latitudes where vertical diffusion is not hindered by Earth's magnetic field, and the ionization takes up a distribution resembling that of a gas, the molecular weight of which is half that of the positive ions (for example, ref. 1); that is, N ∝ e−½z.
