[P-EM10] Dynamics of Magnetosphere and Ionosphere

Thu. May 26, 2022 9:00 AM - 10:30 AM 303 (International Conference Hall, Makuhari Messe)

convener:Yuka Sato(Nippon Institute of Technology), convener:Akimasa Ieda(Institute for Space-Earth Environmental Research, Nagoya University), Akiko Fujimoto(Kyushu Institute of Technology), convener:Shun Imajo(Data Analysis Center for Geomagnetism and Space Magnetism, Graduate School of Science, Kyoto University), Chairperson:Hiroshi Hasegawa(Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Masaki N Nishino(Japan Aerospace Exploration Agency/Institute of Space and Astronautical Science)

This session provides an opportunity to present recent results from satellite and ground-based observations as well as from theoretical and simulation studies on the magnetosphere, ionosphere, and their coupling processes. We invite talks and posters discussing various phenomena related to the magnetosphere-ionosphere system: solar wind-magnetosphere interaction, magnetosphere-ionosphere convection, field-aligned current, magnetic storms/substorms, neutral-plasma interaction, ionospheric ion inflow and outflow, aurora phenomena, and so forth. Discussions on planetary and satellite ionospheres and magnetospheres, future missions, and instrument developments are also welcome.
