CEDAR email: Call for AGU Abstracts: SM020. Ring Current Dynamics and Its Coupling with Other Particle Populations

[Yue Chao]

Dear Colleagues,



We would like to invite you to submit contributions to the ring current
session at the 2024 AGU Fall Meeting (Washington, D.C., 9-13 December
2024).  Abstracts submission link is here:
https://agu.confex.com/agu/agu24/prelim.cgi/Session/226541.

The submission deadline is *July 31st, 2024. *



*SM020. Ring Current Particle Sources, Losses, and its Coupling with Other
Regions*



Earth’s ring current is comprised of electrons and ions from 1 keV to
several hundred keV and regulates the energy density and field
configuration of the magnetosphere. Abrupt changes in this population are
responsible for decreases in Earth's surface magnetic field, serving as an
indicator for geomagnetic storms. The storm-time ring current is linked to
harmful space weather effects, highlighting the need to study its source
and loss processes, and impacts on magnetosphere-ionosphere system. The
instability of ring current plasma provides free energy for generating
various waves. The electromagnetic ion cyclotron waves, magnetosonic waves,
and whistler-mode waves can scatter or heat particles of different species,
resulting in their precipitation to the ionosphere or energization in the
magnetosphere. We invite presentations of theoretical studies, numerical
modeling, and observations to advance understanding of the ring current
dynamics, wave-particle interactions, and the coupling between the ring
current and particle populations in different regimes.



Conveners: Qianli Ma, Cristian Ferradas, Jacob Bortnik, Chao Yue
