Signatures of Coronal Mass Ejections in the Solar Corona

Many theoretical and modeling advances have had success in covering properties associated with initiation, propagation and impact phases of coronal mass ejections (CMEs), leading to a better understanding of CME eruption and kinematics in the interplanetary space. These methodologies include both first principle and (semi-) empirical modeling frameworks to represent CME initiation processes, including insertion of an out-of-equilibrium flux rope, modeling flux emergence, flux cancellation, and/or reconnection scenarios in the low solar corona. Remote sensing and in-situ observations are used not only to study CME related phenomena like eruption mechanism and physical properties, but also for driving, validating, and verifying these modeling efforts.
This session invites contributions on different CME initiation mechanisms, their implementations and the impact of the initial phase on CME eruption, morphology, and propagation in the solar corona. We also solicit submissions on identifying relevant observables (including pre- and post- eruption signatures), associating them to modeled CME properties and strategies on the best use of these observations to constrain and validate models (e.g., coronal waves or dimming phenomena). Observation-based modeling can improve our understanding of the physical processes associated with CMEs and therefore increase the accuracy of space weather predictions. Contributions using recent observations (including ground observations and instrumentation onboard Solar Orbiter, Parker Solar Probe spacecraft) are also encouraged.
