Summary:
The main objective of this proposal is to understand the physical connections between energetic particle populations observed in the vicinity of dipolarization fronts in the near-Earth plasma sheet and those observed in the dipole-dominated inner magnetosphere. Taking advantage of unprecedented multi-point observations by THEMIS, we propose to study the spectral properties, spatial distribution, occurrence rates and spatial and temporal scales of the injections. Typical observed spectra will be used as input parameters for particle-tracing under a transient electric field to calculate the particle paths and spectra in the inner magnetosphere under a variety of conditions and ascertain the importance of such injections. Case studies with three to five THEMIS spacecraft (as well as RBSP, when available) will be used for direct comparisons with the model results. This comparison will make it possible to adjust model parameters, leading to better understanding of the underlying physical processes and driver properties, such as the scale size and duration of the impulse. The proposed study will contribute towards the resolution of an outstanding science question in space physics:Performance Year | Reference | Investigation Type | Actions |
