[P-EM13] Dynamics of the Inner Magnetospheric System

Tue. May 23, 2023 3:30 PM - 4:45 PM 101 (International Conference Hall, Makuhari Messe)

The inner magnetosphere is highly variable due to dynamic variations of energy input from the solar wind through the magnetotail and plasma supply from the ionosphere. This dynamics system is also contributed from cross-regional, cross-scale, and cross-energy coupling processes. Coordinated observations with multi-point satellites measurements, ground-based networks, and theoretical modeling are very essential to revealing the dynamic system. In the 24th and 25th solar cycles, a number of satellites (Van Allen Probes, MMS, THEMIS, DSX, Arase, cubesats, etc.), coordinated ground-based observations (THEMIS-GBO, SuperDARN, EISCAT, magnetometers, riometer, etc), and numerical simulations (global kinetic model, MHD model, micro PIC, hybrid, particle tracing simulations, etc.) have greatly contributed to better understanding the inner magnetosphere system. We invite papers presenting recent results on the inner magnetosphere and its coupling/connection with other regions including the ionosphere and the outer magnetosphere. Papers on new projects (sounding rocket experiments, data assimilation/machine learning, etc.) and future spacecraft missions including cubesats are also welcome.
