Observations of the rise phase of major solar energetic particle (SEP) events have indicated a necessity of constructing hybrid models that would include the complex spatial and temporal evolution of coronal mass ejections (CMEs), their shocks and associated coronal magnetic structures. We report on a new model of SEP acceleration and transport from the solar corona to interplanetary space. The model accommodates results of numerical MHD modeling of CMEs in the magnetic environment of the solar corona and solar wind. Particles are traced with Monte Carlo simulations in a hybrid coordinate system with use of both the diffusion approach and focused transport framework. The model accounts for regular acceleration in the shock front as well as for adiabatic deceleration and stochastic re-acceleration in the downstream region of the shock. The model is aimed at fitting and analyzing stereoscopic SEP measurements including dynamic energy spectra, pitch-angle distributions and ionic compositions.
