Parameterized Real-Time Ionospheric Specification Model PRISM Version 1. 0

Abstract

This study describes the development of a real-time ionospheric model, PRISM, that is based on parameterized physics-based ionospheric models rather than empirical models. PRISM consists of two parts: (1) a database of global ionospheric representations produced by four different ionospheric models developed by Utah State University, the Geophysics Directorate of Phillips Laboratory, and Computational Physics, Inc., and (2) a real-time adjustment algorithm that modifies these ionospheric representations on the basis of ground-based and space-based data. The ionospheric representations in the database are parameterized in terms of Universal Time, season, solar activity, and magnetic activity. The report describes the four physics-based models, the parameterization process, and the real-time adjustment algorithm.
