Climatology of the Earth's inner magnetosphere as observed by the Radiation Belt Storm Probes Ion Composition Experiment (RBSPICE) instrument on the Van Allen Probes spacecraft.

The Radiation Belt Storm Probes Ion Composition Experiment (RBSPICE) instrument on the Van Allen Probes spacecraft measures energetic ion and electron particle populations in a species dependent energy range of 10's of KeV up to an MeV. The instrument separates the ion population into component species of protons, helium, and oxygen. This paper presents a climatological survey of RBSPICE measurements over the life of the mission to date. A comparison of spectrographs of the energetic particle populations (e, p, He, and O) is shown against key standard geomagnetic indices. Also shown is a summary of key electron and ion lower energy events based upon a systematic characterization of the type of event. The analyses of these events provide verification of the difference between electron and ion drift orbits and, based upon characterization schemes, show how the different event categories can vary as a function of L and MLT.
