2D Stochastic Monte Carlo to evaluate the modulation of GCR for inner and outer solar system planets

We developed a 2D Stochastic Monte Carlo model for Cosmic Rays propagation in the Heliosphere. The model solves numerically the transport equation of particles in the heliosphere, including major processes affecting the heliospheric particle transport: diffusion, convection, adiabatic energy losses and drift of particles. We evaluated the modulated flux at several distances from the Sun (i.e. at planetary distances) and compared our results for both solar polarities with measurements of CR protons at the Earth distance, 1 AU.
