Global Plasmaspheric Issues

Abstract

The plasmasphere and the dense plasmas drawn from it into the middle and outer magnetosphere dynamically participates in the transport of energy produced during magnetic storms into the inner magnetosphere and ionosphere. These plasmas are also a tracer of electric fields induced globally by the solar wind and locally through transient phenomena. The outstanding issues related to plasmaspheric plasma in the magnetosphere will be discussed in the context of the anticipated IMAGE mission which, for the first time, will provide global images of this plasma system.
