The effects of cosmic rays modulation on proton spectrum was studied using the HelMod - 2-D Monte Carlo code, that includes a general description of the diffusion tensor, and polar magnetic-field. The Numerical Approach used in this work is based on a set of Stochastic Differential Equations fully equivalent to the well know Parker Equation for the transport of Cosmic Rays. The model description was updated using Proton spectras measured by PAMELA during the last solar minimum.
