9 9 Global Solar Wind Boundary Evaluating the 3D reconstruction at a given spherical radius provides a “global solar wind lower boundary” which can then be extrapolated outward by 3D-MHD models. Results of this extrapolation can be compared with in-situ measurements as a “ground truth” verification of this technique.
