[P-EM12] Coupling Processes in the Atmosphere-Ionosphere System

2025年5月26日(月) 13:45 〜 15:15 303 (幕張メッセ国際会議場)

コンビーナ:細川敬祐(電気通信大学大学院情報理工学研究科)、Liu Huixin(九州大学理学研究院地球惑星科学専攻九州大学宙空環境研究センター)、大塚雄一(名古屋大学宇宙地球環境研究所)、Chang Loren(Institute of Space Science, National Central University)、Chairperson:Bernd Kaifler(German Aerospace Center)、Liu Huixin(九州大学理学研究院地球惑星科学専攻九州大学宙空環境研究センター)

The Atmosphere-Ionosphere (A-I) system forms the so-called near-Earth space. Recent rapidly expanding use of satellite constellations in low Earth orbit (LEO) drives a high demand for better understanding and accurate forecast of the global A-I system for scientific and operational purposes. This session aims to provide a forum for research advances and frontiers related to these aspects, and we invite presentations on global A-I coupling at all temporal and spatial scales. This includes but is not limited to: A-I coupling via atmospheric waves (tides, gravity waves, planetary waves) and trace gases (CO2, O3, H2O), A-I response to Space Weather events (solar flares, CMEs, CIRs), polar-equatorial, inter-hemispheric coupling via TADs/TIDs/disturbance dynamo/penetration electric field, ionospheric plasma irregularities, and ionospheric currents. Observations, theoretical studies, model simulations, data assimilation, instruments development are all highly welcome.
