This session will focus on the studies of 3-D morphology and dynamics of coronal mass ejections or CMEs. The launch of SECCHI coronagraphs on the twin spacecraft STEREO has made possible observations from 2 different vantage points. These observations have been found to be extremely useful in reconstructing the 3-D structures and measuring the true speeds of CMEs, which can lead to improved understanding of the initiation and propagation of CMEs. In particular, 3-D reconstruction of CMEs and associated structures is achievable from COR1 and COR2 coronagraphs and EUVI images. The techniques of 3-D reconstruction, and their applications to observations of CMEs will be discussed. In addition, we invite papers on the interplanetary manifestations of the CMEs identified in the solar wind using in-situ measurements made by instruments aboard STEREO. An inter-comparison of both coronal and in-situ observations made by STEREO with those observed by earlier instruments, for example SoHO and ACE will also be highlighted. In this session, we also invite presentations on new results obtained from STEREO observations of CMEs and ICMEs and their implications on CME initiation and propagation models.
