In recent years, and particularly with the advent of the STEREO mission, many new data analysis techniques have been developed that have improved our ability to track solar wind transients out to distances of 1 AU and beyond. Combining these tracking techniques with complimentary methods such as interplanetary scintillation (IPS) and in-situ spacecraft measurements is advancing our understanding of how these solar wind transients propagate through the heliosphere. There is still much to learn about the links between the Sun and the heliosphere, in particular the origins of the ambient solar wind and solar ejecta, their structure and evolution as they propagate into interplanetary space and their subsequent interactions with planets and other solar system bodies. This session will draw together our current knowledge of the physics within the solar-heliospheric environment, and consider techniques that wil lead to progress in this area of science, with particular emphasis on the exploitation of multiple missions.
