[PEM12-P34] Cross-calibration of high-energy electron observations at geostationary earth orbit
Keywords:space weather forecast, magnetospheric particle distribution, cross-calibration of particle data
Our previous study showed seasonal dependence of sensitivity difference between high energy electron sensor onboard Himawari and that onboard Kodama. We found that this seasonal dependence might be caused by the north-south drift of the Kodama’s orbit. Previous study, we assumed that the orbit of Kodama is aligned with GEO. This result suggests that the detailed orbit information is important for cross-calibration. Based on this cross-calibration procedure, we can produce particle distribution at GEO. In our presentation, some sample events of particle distribution at GEO will be shown, and the future plan for producing particle distribution in the inner magnetosphere using energetic electron data from ARASE(ERG), Van-Allen Probes, and GPS will be introduced.
