Abstract:
In the present contribution the main processes associated with the penetration of cosmic rays through the Earth's atmosphere are discussed. The final particle flux depends on the geomagnetic coordinates, on the altitude and temporal moment of measurement or calculation.
Using the EXPACS code [1], the contributions of neutrons, protons, ions, muons, electrons, positrons and photons, which are potentially essential issues in various experiments, are considered. Because the target and detector are located underground a special attention is dedicated to muons and neutrons the only particles able to penetrate the rock depth. In this analysis the following locations where neutrino experiments are either located or could (potentially) be located: the Mediterranean Sea, Antartica, Lake Baikal, Gran Sasso, Daya Bay, Chooz, Kaiping, Hida, South Dakota, Pyhasalmi, Slanic are considered are considered for flux estimation at Earth’s surface. The time variation of the local cosmic ray fluxes is also estimated.
