[P-EM15] Dynamics of Magnetosphere and Ionosphere

Thu. May 29, 2025 1:45 PM - 3:15 PM 302 (International Conference Hall, Makuhari Messe)

convener:Shun Imajo(Data Analysis Center for Geomagnetism and Space Magnetism, Graduate School of Science, Kyoto University), Yuka Sato(Nippon Institute of Technology), Akiko Fujimoto(Kyushu Institute of Technology), Kazuhiro Yamamoto(Institute for Space-Earth Environmental Research), Chairperson:Shin-ichiro Oyama(Institute for Space-Earth Environmental Research, Nagoya University), Aoi Nakamizo(Applied Electromagnetic Research Institute, National Institute of Information and Communications Technology)

This session provides an opportunity to present recent results from satellite and ground-based observations and 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, instrument developments, and advanced methodology are also welcome.
