摘要 Solar proton events have been recorded based on the criteria when the proton fluxes at energies larger than 10MeV measured by GOES spacecraft at geosynchronous orbit exceeds or equals 10 pfu (particle flux unit) for a continuous time. These events have been observed to affect the atmosphere and ionosphere through the Earth’s poles in the form such as enhanced ionization causing radio signal absorption. Some events with intensified fluxes at higher energies (e.g., >100MeV) may be even possible to cause damages on spacecraft in the magnetosphere. Since the Relativistic Proton Spectrometer (RPS) carried by Van Allen Probes, launched on August of 2012, are able to measure protons with energies above ~ 60 MeV up to ~ 2 GeV, in this study, we analyze available observations from RPS during periods of solar proton events for the Solar Cycle 24. Comparisons in the observed fluxes at different energy levels with the intensities of solar proton events will be made through temporal and spatial analyses. This will enhance our understanding on changes in proton fluxes with energies higher than the order of 100 MeV as well as effects on the radiation belts from solar proton events with different intensities.
