Abstract: | The heliospheric counterparts of coronal mass ejections (CMEs) at the Sun, interplanetary coronal mass ejections (ICMEs),
can be identified in situ based on a number of magnetic field, plasma, compositional and energetic particle signatures as
well as combinations thereof. We summarize these signatures and their implications for understanding the nature of these structures
and the physical properties of coronal mass ejections. We conclude that our understanding of ICMEs is far from complete and
formulate several challenges that, if addressed, would substantially improve our knowledge of the relationship between CMEs
at the Sun and in the heliosphere. |
