A low altitude trapped proton model for solar minimum conditions based on SAMPEX/PET data

We present a low altitude (below about 600 km) trapped proton model for solar minimum conditions (1994-1995), based on measurements made by the Proton/Electron Telescope onboard the SAMPEX satellite. Substantial differences are found with the low altitude part of the AP-8 MIN model: low energy fluxes appear to be overestimated by AP-8 MIN, while the new model predicts higher fluxes than AP-8 MIN for energies above about 30 MeV.
