Abstract:
Plasma sheet injections driven by regions of low flux tube entropy (“bubbles”) have been found to contribute significantly to the inner magnetosphere plasma population. However, the effect of individual injections and how they incorporate into the inner magnetosphere is not well understood. This study extends previous work that used the OpenGGCM-RCM coupled model to track injections by coupling with the Comprehensive Inner Magnetosphere-Ionosphere model (CIMI). Inclusion of the CIMI model provides simulated particle fluxes at radiation belt and plasmasphere energies, as well as the effects of wave interactions. The dependence of injection penetration depth and inner magnetosphere plasma energization on initial bubble parameters is examined. Results are compared to previous modeling results and observational data from THEMIS and the Van Allen Probes.
