Session Proposal: Ring Current Particle Sources, Losses, and its Coupling with Other Regions (AGU25)

SM026
Ring Current Particle Sources, Losses, and its Coupling with Other Regions

Session ID#: 248775

Session Description:
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.
