While electrons and protons experience the same radial diffusion from field fluctuations, their dynamic behaviour in the radiation belts differs mainly because of local wave-particle interactions for electrons and charge exchange for protons. Comparing dynamics of protons and electrons should help us understanding better the balance between acceleration and loss processes during magnetic storms as well as during quiet times.

This session shall focus on recent studies of the effects of wave-particle interactions, radial transport, charge exchange, etc., on the Earth and other planetary radiation belts. We encourage the submission of papers on related modelling, studies revisiting previous missions, ongoing missions such as Van Allen Probes, THEMIS, MMS, and future missions such as ERG and small satellites /cubesat missions and Juno that will explore high latitude radiation environment on Jupiter.
