Recent progress in the understanding of radiation-belt energization and loss processes, as well as ring-current build-up and decay, has shown that the system is highly variable, and relies on a variety of different waves and other transient phenomena to couple the dynamic processes occurring in the inner magnetosphere. Multiple energization and loss process occur simultaneously, over a variety of spatial scales ranging from microscopic wave-particle interactions, to global-scale interactions, and a variety of temporal scales, from milliseconds to hours.

In this symposium, we will focus on the dynamical behaviour of radiation-belt and ring-current particles, the global variability and coupling to the inner magnetosphere, and the nature and spatiotemporal distribution of the underlying waves that control this behaviour.
