[P-EM18] Dynamics of Magnetosphere and Ionosphere

Thu. May 28, 2026 3:30 PM - 5:00 PM 304 (International Conference Hall, Makuhari Messe)

Chairperson:Yamakawa Tomotsugu(Institute for Space-Earth Environmental Research, Nagoya University), Saito Koseki(Department of Geophysics, Graduate School of Science, Tohoku University), Hori Tomoaki(Institute for Space-Earth Environmental Research, Nagoya University)

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.
