Modifications and Improvements to the PRISM and PIM Ionospheric Models

Abstract

This report describes the preliminary design of PRISM Version 2, a parameterized, real-time ionospheric specification model. PRISM was developed for use at the 55th Space Weather Squadron (55SWXS) at Falcon Air Force Base. PRISM consists of the theoretical climatology model, PIM (Parameterized Ionospheric Model), and an algorithm for updating PIM electron density profiles using ground based and spaced data. The new versions of PIM and PRISM will be based on a single, global, physics-based ionospheric model that incorporates the plasmasphere. They will be parameterized in terms of month (rather than season), and with additional climatological parameters augmenting the solar activity and geomagnetic activity parameters of the old version. PRISM 2 will also have an improved data assimilation algorithm. This report also describes modifications to VOACAP to allow it to read and use the PIM or PRISM ionosphere instead of its own internal ionosphere and other updates to the operational version of PRISM.
