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

TL;DR

This paper compares multiple ICME catalogues, analyzes their differences, and constructs a unified catalogue for 2010-2022, enhancing data consistency and understanding of CME characteristics.

Contribution

It introduces an algorithm to merge different ICME catalogues and creates a comprehensive unified catalogue covering 2010-2022.

Findings

High accuracy in merging events across catalogues

Events in all three catalogues tend to have greater duration, speed, and geoeffectiveness

Unified catalogue improves data consistency for space weather studies

Abstract

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 and Cane and CCMC CME Scoreboard ICME catalogues and the SRI RAS solar wind types catalogue, and propose an algorithm 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 catalog is presented on the SINP MSU Space Weather Exchange website: https://swx.sinp.msu.ru/tools/icme_list.php
