HelMod-4 for Predicting Galactic Cosmic Ray Intensities in the Space Radiation Environment

Galactic cosmic rays (GCRs) are one of the radiation sources in the space radiation environment representing a hazard for electronic systems and long-term crewed space missions. In the attempt to mitigate such risks, the appropriate knowledge of cosmic ion fluences is therefore mandatory. In this context, the HelMod-4 model can assess and forecast the GCR ion spectrum long-term variations. In the model, a Monte Carlo approach is used to solve the Parker transport equation to evaluate the effect of the solar modulation on the local interstellar spectra of GCRs during high and low solar activity periods, in the inner and outer heliosphere, at the Earth location, and outside the ecliptic plane. In this work, we present the updated parametrization of the HelMod-4 model with a focus on the descending phase of solar cycle 24, by means of a data-driven approach using the latest high-precision data from AMS-02. We also present how the broader space community could benefit from the model using dedicated web tools.
