RUSCOSMICS Software Package as a Tool for Estimating the Earth's Atmosphere Ionization Rate by Cosmic Ray Protons.

An overview is presented of the possibilities of using the module of the RUSCOSMICS software package designed for calculating the passage of cosmic ray (CR) particles through the Earth's atmosphere. General information on current ways of studying secondary CR fluxes is considered. References are made to works by other groups. Key points of the calculation algorithm are described. Parameterization of initial conditions is analyzed. Typical results obtained in modeling are given. A summary of this work and the outlook for the project are given. [ABSTRACT FROM AUTHOR]
