Abstract :
A statistical model for cumulative solar proton event fluences during space missions is presented that covers both the solar minimum and solar maximum phases of the solar cycle. It is based on data from the Interplanetary Monitoring Platform and Geostationary Operational Environmental Satellites series of satellites, which are integrated together to allow the best features of each data set to be used to the best advantage. This allows the fluence-energy spectra to be extended out to energies of 327 MeV.
