摘要: During recent years it became evident that the climate of Earth is not only determined by terrestrial, in particular anthropogenic influences, but also external parameters. An open question still whether solar radiation or cosmic rays are main agents regarding driving. answer to this requires quantitative modelling all related processes. The present chapter concentrates on ray transport from interstellar medium into Earth’s atmosphere and, thus, interstellar-terrestrial relations. After a discussion significance local spectrum rays, first their dynamical heliosphere considered. Second, propagation within terrestrial magnetosphere studied order determine so-called cut-off rigidities. And, third, interaction with described, an emphasis ionisation and production cosmogenic nuclides. On basis suite models being discussed overview further studies will be possible should help quantify overall effect environment particularly, climate.
