Local acceleration driven by whistler‐mode chorus waves is fundamentally important for
accelerating seed electron populations to highly relativistic energies in the outer radiation
belt. In this study, we quantitatively evaluate chorus‐driven electron acceleration during the
17 March 2013 storm, when the Van Allen Probes observed very rapid electron acceleration
up to several MeV within~ 12 hours. A clear radial peak in electron phase space density
(PSD) observed near L*~ 4 indicates that an internal local acceleration process was …

Local acceleration driven by whistler-mode chorus waves is suggested to be fundamentally
important for accelerating seed electron population to ultra-relativistic energies in the outer
radiation belt. In this study, we quantitatively evaluate chorus-driven electron acceleration
during the 17 March 2013 storm, when Van Allen Probes observed very rapid electron
acceleration up to multi MeV within∼ 15 hours. A clear peak in electron phase space
density observed at L∗∼ 4 indicates that the internal local acceleration process was …
