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

Mon. May 22, 2023 1:45 PM - 3:00 PM 106 (International Conference Hall, Makuhari Messe)

convener:Huixin Liu(Earth and Planetary Science Division, Kyushu University SERC, Kyushu University), Yuichi Otsuka(Institute for Space-Earth Environmental Research, Nagoya University), Loren Chang(Department of Space Science and Engineering, National Central University), Yue Deng(University of Texas at Arlington), Chairperson:Christina Arras(TU Berlin, Germany), Atsuki Shinbori(Institute for Space-Earth Environment Research (ISEE), Nagoya University)

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.
