Analysis of Differences between ICME catalogues and Construction of a Unified Catalogue

Multiple magnetic and kinetic solar wind plasma parameters are used to detect coronal mass ejections (CMEs) as they travel through the heliosphere. There are various interplanetary CME (ICME) catalogues, but due to differences between their ICME identification criteria they can significantly vary. In this paper we analyze Richardson & Cane and CMC CME Scoreboard ICME catalogues and the SRI RAS solar wind types catalogue, and propose an algorith of merging them. A unified catalogue is constructed for 2010 to 2022. The resulting catalogue is completed with data from the OMNI database. Analysis of the unified catalogue demonstrated high accuracy when merging events present in multiple catalogues and a tendency of events defined in all three initial catalogues to demonstrate greater duration, speed and geoeffectiveness. The catalogue is presented on SINP MSU’s Space Weather Exchange website: https://swx.sinp.msu.ru/tools/icme_list.php.
