Electron distribution function and ion concentrations in the earth's lower ionosphere from BoltzmannFokkerPlanck theory
Abstract
Using the BoltzmannFokkerPlanck method and the local approximation we derive coupled nonlinear equations for the electron and ion concentrations and the energydependent electron distribution function in the Earth's lower ionosphere. These equations are new and give the appropriate generalization of the standard electronion continuity equations in the local approximation when electronneutral particle impact ionization is treated rigorously. We report stable, numerical solutions to these equations and compare our calculated electron concentration to the experimentally determined result for a rocket experiment where the electron concentration and solar EUV spectral flux were measured simultaneously.
