Radial transport versus local acceleration: The long-standing debate

On 28 July 2021, within the Geospace Environment Modeling Virtual Summer Workshop, a joint panel discussion organized by the "System Understanding of Radiation Belt Particle Dynamics through Multi-spacecraft and Ground-based Observations and Modeling" and "ULF wave Modeling, Effects, and Applications" focus groups was held. The panelists, organizers, and the audience discussed the nature and unresolved questions of radiation belt electron flux enhancements.

In this commentary we provide the outcomes of this discussion.
