For comprehensive global modeling of cosmic rays modulation in the heliosphere, it is essential
to have a sound transport theory, and reliable numerical schemes with appropriate boundary
conditions. For the description of the solar modulation process, and the propagation of the
particles inside the heliosphere, Parkers transport equation is widely used. The correct and precise
solution of this equation also must take into consideration errors. That’s why the presented work
particularly focused on the estimation of the errors of the SOLARPROP model, based on the input
parameters range, and statistical errors for these numerical solutions of 2D Parkers equation by
stochastic differential equation method to suggest the safe simulation strategy for spectra evaluation
at 1 AU.
