2D stochastic simulation model of cosmic ray modulation: comparison with experimental data
Abstract
We developed a 2D stochastic simulation model for heliospheric propagation of galactic cosmic rays. The model solves numerically the transport equation of particles in the heliosphere. In the calculation we use also drift effects which are included through analytical effective drift velocities. We estimated the cosmic rays spectrum at 1 AU using this model formalism. The calculated spectra are compared with other models (CREME96) and with experimental data (IMP8 and AMS) for positive (A>0) and negative (A<0) solar periods.
