[P-EM12] Dynamics of the Inner Magnetospheric System

Sat. Jun 5, 2021 1:45 PM - 3:15 PM Ch.05 (Zoom Room 05)

convener:Kunihiro Keika(Department of Earth and Planetary Science, Graduate School of Science, The University of Tokyo), Yoshizumi Miyoshi(Institute for Space-Earth Environmental Research, Nagoya University), W Lauren Blum(University of Colorado Boulder), Yuri Shprits(Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences), Chairperson:Yikai Hsieh(Reserach Institute for Sustainable Humanosphere, Kyoto University)

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, and cross-energy couplings are the key processes for understanding this dynamical system. Coordinated observations by multi-satellites and ground-based observations are very essential to revealing these processes. In the 24th and 25th solar cycles, 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. We invite papers on recent results of the inner magnetosphere and/or its coupling with the other regions including the ionosphere and the outer magnetosphere. Presentations on new projects such as sounding rocket experiments and data assimilation/machine learning are also welcome.
