Session SWR2 - Interplanetary Coronal Mass Ejections and Solar Energetic Particles

Coronal mass ejections (CMEs) and their interplanetary counterparts (ICMEs) are of key interest in the field of solar-terrestrial relations. They are among the largest and most energetic transients in the heliosphere, and are main drivers of the most intense geomagnetic storms. CMEs and ICMEs can generate shock waves, even very low in the solar corona, producing significant fluxes of solar energetic particles (SEPs). They are also important drivers of relativistic electron enhancements in the radiation belts surrounding the Earth. Solar flares associated with CME eruptions can in turn have important impacts (UV radiation, particles) on the Earth's atmosphere. There is thus a strong need for realistic data-driven simulations of CMEs/ICMEs and their associated shocks and particle environment using a variety of theoretical, physics-based and semi-empirical models. Additionally, models can be complemented with the use of data from novel missions such as Parker Solar Probe and Solar Orbiter, wide-field heliospheric observations such as those provided by the STEREO mission, and enhanced catalogues such as HELCATS. In this session, we invite observational, theoretical, and modelling contributions on ICME-related topics, including ICME propagation in the heliosphere, the interaction of ICMEs with Earth and/or other planets, the link between CMEs and ICMEs, the generation and transport of SEPs by CME-driven shocks, and the forecasting of ICME and SEP occurrence and characteristics.
