Observation and Modeling of Geostationary Orbit Electron Energization Induced by Enhanced Dayside Whistler-Mode Waves

We provide correlated observations of enhanced dayside whistler-mode waves and energetic electron acceleration collected by the CLUSTER and GOES satellites during the 23～24 September 2001 storm. Energetic （〉0.6 MeV） electron fluxes are found to increase significantly during the recovery phase and th...

Summary:We provide correlated observations of enhanced dayside whistler-mode waves and energetic electron acceleration collected by the CLUSTER and GOES satellites during the 23～24 September 2001 storm. Energetic （〉0.6 MeV） electron fluxes are found to increase significantly during the recovery phase and the main phase, by a factor of～50 higher than the prestorm level. These high electron fluxes occur when strong dayside whistler-mode waves are present. Two-dimensional （2D） numerical simulations are carried out and the results demonstrate that the dayside whistler-mode wave can contribute to such enhancements in electron flux within 24 h, consistent with the observation.
