AB: The interpretation of Solar Energetic Particle or SEP events detected by STEREO will require a "global" picture that is consistent with the underlying solar wind context. One approach to such a model is under development by the CISM (Center for Integrated Space Weather Modeling) group. This model uses a guiding-center technique to follow ions in the >10 MeV energy range in the magnetic fields produced by CISM heliospheric MHD simulations. The model accommodates a variety of source descriptions, including flare-related sources at the Sun and those from traveling interplanetary shocks described by the MHD models as a consequence of coronal transients propagating to 1 AU. The shock source descriptions will eventually be based on parameterizations derived from local ion-kinetic hybrid simulations of shocks covering the parameter space (Mach number, plasma beta, shock normal angles) of interest. The advantage of this approach is its relative generality in that it can accommodate any complicated coronal and solar wind field and source descriptions the MHD models (and observations) may require.
