AB: We present a long-term validation of a global, 3D MHD model for the solar corona and the solar wind. The model is driven by high resolution MDI magnetograms and is constrained by the empirical Wang-Sheeley-Arge (WSA) model. The model provides a three-dimensional steady-state structure of the heliosphere between the Sun and the Earth for a particular Carrington Rotation. We use the model to obtain the large-scale context for the information we collect from multipoint spacecraft observations and large-scale remote sensing imagine of the solar corona and the heliosphere. For the long-term validation of the model, we compare the result with ACE data and the available STEREO data.
