The high-energy charged particles entering the Earth's environment from interplanetary space have the significant effect on the space weather. We propose an improved model, which generalizes the differential D(E) and integral D(>E) spectra of galactic (GCR) and anomalous cosmic ray (ACR) protons and heavier elements during the 11-year solar cycle. The model takes into account the cosmic ray (CR) modulation by the solar wind and numerous solar and heliospheric events during different levels of solar activity. Modulated energy spectrum of galactic cosmic rays is compared with force field approximation. The difference is in the order of 1.5 %. The model solutions are compared with IMAX-92, CAPRICE-94 and AMS-98 measurements. This computed analytical model gives practical possibility for investigation of experimental data from measurements of galactic cosmic rays and their anomalous component. The obtained parameters are used for determination the profiles of the ionization in the ionosphere and middle atmosphere.
