[P-EM19] Dynamics of the Inner Magnetospheric System

convener:Kunihiro Keika(Department of Earth and Planetary Science, Graduate School of Science, The University of Tokyo ), Aleksandr Y Ukhorskiy(Johns Hopkins University Applied Physics Laboratory), Yoshizumi Miyoshi(Institute for Space-Earth Environmental Research, Nagoya University), Lynn M Kistler(University of New Hampshire Main Campus)

The inner magnetosphere is highly variable because dynamical
variations of incoming energy from the solar wind, magnetospheric tail,
and the ionosphere. Cross-regional/cross-scale/cross-energy couplings
are key processes to understand this dynamical system, and coordinated
observations by multi-satellites and ground-based observations are
very essential to reveal these processes. In the 24th solar cycle,
a number of satellites such as Van Allen Probes, MMS, THEMIS, DSX and
Arase, coordinated ground-based observations (THEMIS-GBO, SuperDARN,
EISCAT, magnetometers, riometer, etc), and numerical simulations
(global kinetic model, MHD model, micro PIC, hybrid simulations) have
successfully investigated the inner magnetosphere system. Papers on recent results
on the inner magnetosphere and/or its coupling with the other regions,
including the ionosphere and the outer magnetosphere are invited. And
presentations on new projects for the inner magnetosphere are also
welcome.
