A New Global Core Plasma Model of the Plasmasphere

Abstract:

The Global Core Plasma Model (GCPM) is the first empirical model for thermal inner magnetospheric plasma designed to integrate previous models and observations into a global, continuous in value and gradient, representation of typical total densities. New information about the plasmasphere, in particular, makes possible significant improvement. The IMAGE Mission Radio Plasma Imager (RPI) has obtained the first observations of total plasma densities along magnetic field lines in the plasmasphere and polar cap. Dynamics Explorer 1 Retarding Ion Mass Spectrometer (RIMS) has provided densities and temperatures in the plasmasphere for five ion species. These and other works enable a new more robust empirical model of thermal in the inner magnetosphere that will be presented.
