Abstract
Understanding the evolution of Coronal Mass Rejections is a challenging endeavor. Imagers provide snapshots of the eruptions, in-situ instruments provide a one-dimensional time series during encounters, theories are not up to date with current observations, and there is a lack of dedicated missions providing multi-spacecraft measurements. All of these factors are severely impacting our understanding of the ever-changing dynamics of CMEs during evolution. However, a wealth of valuable data exist and novel techniques to extract information are always needed. In this work, we discuss different approaches to making the most of the available data, through data analysis techniques, improving fitting techniques, and utilizing different spacecraft configurations. We also present recommendation on the needed measurements to adequately study and probe the structure and evolution of CMEs.
