Comparing L1 to near-Earth data for magnetosheath jet studies

This study explores large-scale solar wind structures and differences in observations between measurement points at L1 and near Earth. Specifically, we focus on coronal mass ejections (CMEs) and stream interaction regions (SIR) together with their distinct substructures. Our study is based on existing CME/SIR lists of events defined by Koller et al. [2022] in OMNI data. For the given time ranges, we compare timing and appearance for the structures in the solar wind plasma and magnetic field parameters as probed by ACE/Wind, OMNI, and THEMIS. Our approach involves creating a database of identified structures, especially those observed by multiple spacecraft, facilitating statistical analysis. Matrix profiles will be employed to unveil recurring patterns and relationships among the substructures measured at different locations. This research will contribute to a more comprehensive understanding of solar wind dynamics and magnetospheric responses to the specific structures which is especially important for magnetosheath jets which are short-lived pressure enhancements.
