Description
Understanding the heliospheric modulation of galactic cosmic rays is essential for studying the acceleration and propagation processes of these particles, as well as for establishing models of radiation exposure and associated risks in space missions. Here we present our efforts in the development of an effective data-driven model describing the time- and energy-dependent solar modulation effects for cosmic-ray protons, nuclei, and their antiparticles. In particular, we present our numerical description of the transport mechanisms of charged particles in the heliospheric turbulence, their relationships with observations of solar activity, our subsequent evaluations of radiation doses in the low-Earth orbit. We discuss the role of the recent multichannel data from the AMS-02 experiment in constraining the model and revealing important details of the solar modulation phenomenon.
