Both interplanetary scintillation (IPS) and Thomson-scattering observations from the U.S. Air Force/NASA Solar Mass Ejection Imager (SMEI) allow a determination of velocity and density in the inner heliosphere and its forecast from remote-sensing heliospheric observations. Recent solar missions, such as Hinode, STEREO, and SDO, and resultant modeling analysis using these data enhance our ability to measure detailed aspects of specific solar events, including their outflow and three-dimensional structure. Current success in this 3D heliospheric endeavor includes the analysis of heliospheric structures that are also measured in situ: interplanetary Coronal Mass Ejections (CMEs), shocks, solar co-rotating structures, and the energy transport provided by solar wind plasma throughout the heliosphere. This report highlights a portion of the work on this multi-faceted topic.
