000006978 520__ $$aCoronal Mass Ejections (CMEs) are large-scale solar eruptive events originating from close field regions of the Sun, and the most energetic phenomenon in the heliosphere. Even though CMEs have been largely studied in the last several decades, and despite significant advances in our knowledge about them, a lot remains unknown about their internal structure, dynamics, and how they link to their interplanetary counterparts, the Interplanetary CME, or ICMEs. In the present work, we analyze Earth-directed CMEs that occurred in 2022, where the availability of data in different viewpoints allows for a comprehensive analysis and insight into the evolution of them and their link with their interplanetary counterpart, or ICME. We employ different space-based observations, with a highlight in the novel data from the Extreme Ultraviolet Imager (EUI), onboard Solar Orbiter (SolO). The large field of view (FOV) of EUI’s 174 Å and 304 Å telescopes provides us with a full picture on the transition between the corona and the heliosphere. The modeling of the CMEs was performed with the state-of-the-art 3D magnetohydrodynamic (MHD) heliospheric model EUHFORIA (EUropean Heliospheric FORecasting Information Asset). Non-magnetized and magnetized CME models were test within EUHFORIA environment in order to qualitative assess their performance. Results show that the non-magnetized model describes better the arrival time of the interplanetary structure. The magnetized models showed a better description of the magnetic structure of the ICME, however these values are still considerably lower than observed and further study and improvement is required.
