Utilizing galactic cosmic rays to understand the Sun-to-Earth evolution of CMEs

Traditionally, to identify ICMEs in the in-situ measurements, mostly plasma and magnetic field measurements are regarded. However, one of the very common in-situ signatures of ICMEs, as well as other interplanetary transients are Forbush decreases (FDs), i.e. short- term reductions in the galactic cosmic ray (GCR) flux. FD phenomena are caused by the interaction of GCRs with a magnetic structure, therefore it is expected that different types of interplanetary substructures cause different types of GCR depressions, allowing us to distinguish between shock/sheath, flux rope and SIR-type of FDs. Moreover, since the interaction of GCRs and CME magnetic structure (presumably flux rope) occurs all the way from Sun to Earth, FDs should also reflect the evolutionary properties of CMEs, which is supported by the results from recent modeling efforts (Dumbovic et al., 2018, ApJ). The evolutionary process of different magnetic structures in interplanetary space will be discussed in the scope of selected case studies, utilizing a number of multi-instrument and multi-spacecraft observations, together with modelling. This research has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 745782.
