The ESP model predicts integral omnidirectional solar
proton fluences for interplanetary space at 1 astronomical
unit (AU). The model will be expanded to include attenuation
by the magnetosphere for geocentric orbits and for distances
outside of the magnetosphere other than 1 AU. The energy range
of the statistical model is > 1 to > 100 MeV. Unfortunately,
satellite instrument measurements for higher energies are not
sufficient for a true statistical model. Therefore, for
energies from > 100 to > 300 MeV, an empirical approach was
taken to the modeling based on spacecraft measurements for
solar cycle 22.
