Abstract:
The MagEIS and REPT sensors make comprehensive measurements of energetic particle fluxes and pitch angle distributions during periods of ULF and EMIC wave activity observed by the Van Allen Probes. These waves are thought to play important roles in the radial transport and energization of particles and also important roles in the loss of electrons from the radiation belts. There have been observations of particle responses to ULF waves by electrons like that of Hao et al. 2014 and ULF waves have been correlated with electron precipitation observed by the BARREL mission (Halford et al., 2015). There are observations of resonant interactions between the particles and waves such as those published by Claudepierre et al., 2013 and Dai et al, 2013, plus observations relating EMIC waves to losses of relativistic electrons like that of Usanova et al., 2014 and Zan et al., 2014. Observations like these will be reviewed from the perspective of the particle measurements on the Van Allen Probes. In addition we will give a short summary of measurement improvements planned for the Van Allen Probes extended mission that will better support future particle comparisons with the low frequency waves.
