Article Synopsis
- - The Van Allen Probes mission used a distributed operational model where the Mission Operations Center (MOC) managed overall tasks while individual instrument-specific Science Operations Centers (SOCs) focused on data acquisition, processing, and instrument performance for their specific instruments.
- - Significant collaboration between the instrument SOCs and the project science team led to crucial discoveries through coordinated observations and cross-calibration of instruments during the mission.
- - Key lessons learned emphasized the value of having dedicated SOCs, which improved the quality and timeliness of instrument data for scientists studying magnetospheric and radiation belt phenomena.
We present observations of the radiation belts from the Helium Oxygen Proton Electron and Magnetic Electron Ion Spectrometer particle detectors on the Van Allen Probes satellites that illustrate the energy dependence and L shell dependence of radiation belt enhancements and decays. We survey events in 2013 and analyze an event on 1 March in more detail. The observations show the following: (a) at all L shells, lower energy electrons are enhanced more often than higher energies; (b) events that fill the slot region are more common at lower energies; (c) enhancements of electrons in the inner zone are more common at lower energies; and (d) even when events do not fully fill the slot region, enhancements at lower energies tend to extend to lower L shells than higher energies.
