Challenges in Magnetosphere-Ionosphere-Thermosphere Coupling: Magnetospheric Energy/Momentum Input and Their Impact on High-Latitude Ionospheric Electrodynamics II Posters

Submit an Abstract to this Session



Session ID#: 22291

Session Description:
Magnetosphere–ionosphere (MI) and ionosphere–thermosphere (IT) are often studied separately by the magnetosphere and aeronomy researchers, although strong coupling of the magnetosphere– ionosphere–thermosphere (MIT) is widely recognized in both communities. This session addresses current understandings and challenges in the MIT coupling dynamics with emphasis on the magnetospheric energy/momentum input and their impact on the high-latitude ionospheric electrodynamics. Field-aligned currents, auroral precipitation, Poynting flux, and magnetospheric waves can have significant impacts on the MIT coupling, especially during strong geomagnetic activities. Studying their spatiotemporal dynamics, energy/momentum deposition patterns, and direct impacts on the high-latitude ionosphere (ionospheric upflows, electric fields, conductances, Joule heating, etc) is a key first step to understand the MIT coupling dynamics as a whole global system. This session invites observations, simulations, theory, or any combination of the three. With our counterpart MIT dynamics session in SPA-Aeronomy, we seek to create synergy between the MI and IT communities.
