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. </span></p>
