swr02 Interplanetary CMEs and Solar Particle Events

Conveners: Luciano Rodriguez (Royal Observatory of Belgium), Sergio Dasso (University of Buenos Aires) and Camilla Scolini (University of New Hampshire)

Interplanetary Coronal Mass Ejections (ICMEs) are of key interest in the field of solar-terrestrial relations. They are the main drivers of the most intense geomagnetic storms. CMEs can produce shock waves, driving them even from very low in the solar corona, and producing significant fluxes of solar energetic particles (SEPs). They are also important drivers of relativistic electron enhancements in the radiation belts surrounding the Earth. Flares in turn can have an important impact (UV radiation, particles) on the Earth's atmosphere. There is thus a strong need for realistic and data-driven modelling of CMEs/ICMEs using a variety of theoretical, physics-based and semi-empirical models, such as heliospheric models like EUHFORIA, ENLIL and SUSANOO. Furthermore, these models can be complemented with the use of data from novel missions like Parker Solar Probe, modern observations such as those from the heliospheric imagers onboard STEREO, and the use of enhanced catalogues such as HELCATS.

In this session, we invite observational, theoretical, and modelling contributions that address the following topics:

  • ICME propagation in the heliosphere, the interaction of ICMEs with Earth and/or with other planets.
  • The link between CMEs and ICMEs.
  • Generation and transport of SEPs by CME-driven shocks.
  • Forecasting of ICMEs and SPEs occurrence and characteristics
  • SEP environments and their effects on spacecraft
