KEYWORDS - remote sensing, in-situ, multi-view point data, inner heliosphere, large-scale solar disturbances;

The launch of STEREO, at the end of 2006, heralded the start of a new era in the observation of the solar system. Together with SoHO, located at a fixed position at L1, STEREO has continuously provided multiple views of large-scale phenomena propagating through the inner heliosphere. With this unprecedented combination of remote-sensing and in-situ observations, in particular, we have been able to gain a much deeper understanding of the 3-dimensional nature of large-scale inner heliospheric structures such as coronal mass ejections (CMEs) and stream/corotating interaction regions (SIRs/CIRs). But what have we gleaned about the limitations of single-viewpoint observations? How can we apply that knowledge in a future with, potentially, only single-spacecraft observations? Moreover, what are the implications for the design of future multi-viewpoint missions?

In this session, we invite observational, theoretical, and modeling contributions that address these questions and cover studies on the evolution, propagation and morphology of large-scale structures (CMEs, SIRs & CIRs) from single- or multi-view point observations at any wavelength.
