RAY TRACING WITH REALISTIC IONOSPHERIC MODELS.

Abstract

Methods for refining a raytracing program are described. The task includes development of electron density profiles capable of simulating fine points in local disturbances, as well as finding an improved and more economical method of data reduction for electron density input to the raytracing program. An error and time analysis was completed in order to test the integration methods used. The electron density profiles were introduced to the raytracing program in tables, which were, in turn, generated by several other programs. The maximum electron density as a function of geomagnetic longitude and colatitude was generated for a given month, year and hour using the National Bureau of Standards predictions. Methods for obtaining the actual profile of electron density versus altitude from ionograms at various geomagnetic points were attempted.
