This session covers observational, theoretical and modelling studies in the Earth's magnetosphere region inside 10Re. This region is composed of three populations of coexisting charged particles: the plasmasphere (few eV particles), the ring current (few 10 keV particles) and the radiation belts (MeV particles). Those populations are interacting together by means of electromagnetic fields, currents, and wave-particle interactions and their dynamics are closely related to the solar wind conditions. Consequently, to accurately model the inner magnetosphere, one needs to take into account all theses interactions and interconnections. The purpose of this session is:
(1) the coupling between the plasmasphere, the ring current and the radiation belts (scientific improvements as well as models coupling efforts),
(2) the plasmapause position and shape,
(3) the inner magnetosphere evolution in relation to the magnetic activity,
(4) the near-Earth plasmasheet composition and its impact on the evolution of the inner magnetosphere.
In this session, the waves can be used as signature of processes, shapes or movements of boundaries and structures. Presentations of particular events as well as statistical studies and modelling efforts are welcome.
