Global Processes that Determine Cosmic Ray Modulation. 4. Anomalous Cosmic Rays and the 22 Year Solar Modulation Cycle

Abstract

We compare recent two-dimensional simulations of anomalous and galactic cosmic rays with recent observations of radial variations and energy spectra in the outer heliosphere using data from the Voyager and Pioneer spacecraft. The simulations show quite reasonable agreement with observations and give significant additional support the present paradigm of cosmic-ray transport and acceleration in the heliosphere as presented in the introductory talks.
