SM001: Advances in Understanding and Modeling the Ring Current and Its
Coupling with Other Particle Populations



The terrestrial ring current is comprised of ions and electrons from a few
keV to several hundred keV and plays an important role in regulating the
energy density and field configuration of the magnetosphere, particularly
during geomagnetic storms. The instability of ring current plasma provides
free energy for various waves (e.g., EMIC, magnetosonic, and whistler
waves), which can heat or pitch-angle-scatter various other plasma
populations through wave-particle interactions and result in plasma
energization or loss via precipitation. The subsequent precipitation
modifies the ionospheric conductance, which in turn changes the
magnetospheric electric potential pattern. Understanding the coupling
processes between the ring current and other particle populations is
crucial to modeling the inner magnetosphere. We invite presentations on
progress of the ring current interactions with and feedback from other
populations (e.g., plasmasphere, radiation belts, ionosphere and neutral
atmosphere). Contributions including theoretical studies, numerical
modeling, observations from satellite and ground-based missions are
welcome.
