Empirical model of galactic cosmic ray particle fluxes based on the experimental data in solar cycles 21–24
2017 August 16
Fundamentals of a new model developed for predicting GCR particle fluxes during space missions are discussed. The model is based on the data set measured onboard spacecraft and stratospheric balloons from 1970s till 2015. The model describes fluxes of GCR particles with charge z from 1 to 28 and energy from ~80 MeV/nucleon up to 100 GeV/nucleon in the interplanetary space at heliocentric distance ~1 AU as a function of solar activity (averaged sunspot number).
