AB: The STEREO (Solar TErrestrial RElations Observatory) mission will employ two nearly identical spacecraft to study CME initiation and evolution through the inner heliosphere and understand how energetic particles are accelerated in the corona and solar wind. To accomplish these goals, one spacecraft will drift ahead of Earth and the other will trail behind, leading to a unique set of stereoscopic measurements of the solar environment. In this study use global MHD simulations of CME initiation and evolution to anticipate similarities and differences between measurements that will be made by the two STEREO spacecraft during the lifetime of the mission. In addition, we attempt to use these same simulated observations to reconstruct the three-dimensional properties of CMEs and the ambient solar wind. We assess to what extent this procedure is successful by comparing the reconstructed results with the original global simulation results. Finally, we demonstrate a prototype GUI-driven tool that merges STEREO spacecraft trajectories and viewpoints with our simulations to provide a global context for interpreting STEREO observations.
