Abstract

A model of high energy protons for low altitude (below 800 km) mission specification was developed. This model is based on the long duration NOAA measurement series. We used only the highest omnidirectional channel from SEM on board the old NOAA satellites, and the corresponding channel from SEM-2 on board the new NOAA ones, as the other channels are contaminated by electrons. This gives us a basis for the model for E > 82 MeV protons. This model was extended in energy by using ICARE-NG measurements on board JASON-2 and HEPAD measurements on board NOAA-6. It gives integrated proton flux in the range 80-600 MeV at altitudes lower than 800 km along the solar cycle.
