ring current particles, and plasmaspheric particles. Their energy range varies from eV to several MeV, and the interplay among the charged particles
provide feedback mechanisms which couple all those populations together. Ring current particles can generate various waves, for example, EMIC waves
and chorus waves, which play important roles in the dynamic evolution of the radiation belts through wave-particle interactions. Ring current
electrons can be accelerated to relativistic radiation belt electrons. Plasmaspheric particles can also affect these processes. In addition,
precipitation of ring current and radiation belt particles will influence the ionosphere, while up-flows of ionospheric particles can affect dynamics
in the inner magnetosphere. Understanding these coupling processes is crucial. We invite presentations on recent progress concerning these
coupling processes. Contributions from all relevant fields, including theoretical studies, numerical modeling, observations from satellite and
ground-based missions, such as Van Allen Probes, Arase, THEMIS, MMS, Cluster, SuperDARN, magnetometer, optical imagers, and IS-radars, are
welcome.</div></div><div align="left"><br></div>-- <br>Dedong Wang<br>Postdoctoral Researcher<br>Department 2 Geophysics/Section 2.8 Magnetospheric
