AB: Solar Mass Ejection Imager (SMEI) observations of the inner heliosphere have been carried out on a routine basis since shortly after its launch on January 6, 2003. By employing a kinematic model of the solar wind, we reconstruct three-dimensional (3D) solar wind structures from multiple observing lines of sight through the outward-flowing solar wind. This model allows us to extract solar wind densities from the SMEI white-light observations and to compare these to multi-point in situ "ground truth" solar wind measurements from instruments aboard the Ulysses, STEREO, ACE, and Wind spacecraft. This facilitates improvements to our 3D reconstruction technique by comparing these reconstructions at multiple points in the inner-heliosphere. Our observations show heliospheric structures globally, and because of this, our reconstructions provide us with a better understanding of the structure and dynamics of the interplanetary environment around each spacecraft, and how these structures are connected back to the Sun.
