Specification of the radiation belt slot region: comparison of the NASA AE8 model with TSX5/CEASE data

Abstract

The NASA AE8 models are compared with 4 years of CEASE data from the TSX-5 satellite, with a focus on the radiation belt slot region. The current 4 years of the TSX5 mission is divided into solar cycle phase, with CEASE models developed for the solar maximum and declining phases. It is found that the AE8 models predict slot fluxes that are orders of magnitude less than that observed by TSX5/CEASE.
