Vertical distribution of electron density in the daytime subauroral ionosphere
Abstract
Vertical electron-density profiles measured in the daytime subauroral E-region are presented. The electron density was measured via high-frequency impedance probe in a series of rocket experiments. A semiempirical model is then used to calculate the electron density and the ion production rate for various sources. It is shown that, even in daytime conditions, the ionization by precipitating electrons has a substantial effect on the formation of the subauroral E-region, leading to the disappearance of the valley in the interlayer region characteristic for the midlatitude ionosphere.
