Modeling of Cosmic-Ray Transport Processes

Abstract

The main task has been the development, testing, and data comparison of a global time dependent and three dimensional heliospheric transport code of galactic cosmic rays. While the code is based on current standard and established theory of solar modulation of galactic cosmic rays, it is far more computationally demanding than what a typical application oriented study may require. The purpose for developing such a code was to afford the group a fully three dimensional solar modulation model by which a computationally efficient parametric set of simulated data can reliably and efficiently be developed. This development should afford the group both qualitative and quantitative advantage in this regard and relative to modulation codes currently available to the group which tend to be rudimentary one dimensional codes. The report is in 4 sections: (1) description of the basic physical model the new three dimensional transport code is based upon, (2) numerical implementation and various algorithms of the code, (3) sample calculations and comparison to available data, and (4) direction and recommendations for future work.
