Ch.04_1
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)
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.
