Modeling of secondary cosmic ray spectra for 23 and 24 Solar Cycles

The SecondaryCR model evaluates secondary particles spectra of electrons, positrons, muons, gammas, protons, neutrons, etc. in the Earth’s atmosphere at different positions, altitudes and times during the 23rd and 24th solar cycles. We combine the model of secondary cosmic rays production in the Earth’s atmosphere from existing models evaluating particles transport in heliosphere and magnetosphere and Corsika model [1] for interaction of primary cosmic rays with the atmosphere. For evaluation of spectra at 1AU on magnetopause we use mainly the results of HelMod model [2]. Transparency of magnetosphere was obtained by GeoMag model [3]. The evaluation of muon fluxes and spectra on the ground over the globe during 23nd and 24rd solar cycle were simulated. Comparison between hadronic models used in Corsika and comparison with BESS data were performed.
