A COMPUTER PROGRAM FOR VLF RAY TRACING IN A MODEL IONOSPHERE,

Abstract

The ray tracing equations and expressions necessary to evaluate these equations for a model ionosphere with a centered dipole magnetic field and an H+, He+, O+, e- diffusive equilibrium concentration model are given and discussed. A basic computer program for the numerical calculation of ray paths in a meridian plane is listed and explained. An additional routine to calculate point-to-point ray paths is briefly described. Examples are given of the computer printout for this ray tracing program and of a plotted ray path. (Author)
