ARGOS/EUVIP Data Development and Utilization
Abstract
Our long term goal is to understand the density structure of the Earth's plasmasphere and the physical processes that contribute to the formation of the plasmapause. Of particular interest is the coupling between the plasmasphere and the ionosphere, the use of global helium images to obtain the density structure, and the physical constraints that restrict any theoretical model. We wish to refine our current model of the plasmasphere, the Multi-Species Kinetic Model of the Plasmasphere (MSKPM), using numerical models for both the topside ionosphere and the large-scale convection electric field. We also wish to validate MSKPM using the data from the Extreme Ultraviolet Imaging Photometer (EUVIP) instrument on the Advanced Research and Global Observation Satellite (ARGOS), as well as from the Extreme Ultraviolet (EUV) instrument on the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite. Both EUVIP and EUV will measure the 30.4 nm sunlight scattered by helium ions in the topside ionosphere and the plasmasphere. Inversion of this data (Meier et al., 1998) is necessary to recover the density structure and any parameters that govern the density structure.
