[P-EM11] Dynamics of the Inner Magnetospheric System

Wed. May 25, 2022 10:45 AM - 12:15 PM 303 (International Conference Hall, Makuhari Messe)

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

The inner magnetosphere is highly variable due to dynamic variations of energy input from the solar wind through the magnetotail and plasma supply from the ionosphere. Cross-regional, cross-scale, and cross-energy couplings are the key processes for understanding this dynamic 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 (Van Allen Probes, MMS, THEMIS, DSX, Arase, etc.), coordinated ground-based observations (THEMIS-GBO, SuperDARN, EISCAT, magnetometers, riometer, etc), and numerical simulations (global kinetic model, MHD model, micro PIC, hybrid simulations, etc.) have successfully investigated the inner magnetosphere system. We invite papers on recent results of the inner magnetosphere and its couplings/connections with the other regions including the ionosphere and the outer magnetosphere. Papers on new projects (sounding rocket experiments, data assimilation/machine learning, etc.) and future spacecraft missions are also welcome.
