Modeling CME Evolution from Sun to Earth Using a Very Large Simulation Database

The nature of coronal mass ejection precursor magnetic structure and eruption triggers has implications for the properties of the erupting CME, including its mass, size, velocity, and topology; properties which in turn affect the CMEs evolution in the solar wind and ultimate space weather impact at 1 AU. We present forward-modeled coronal, heliospheric, and in-situ manifestations of the CME, and discuss how such observations may constrain models of CME triggers and improve space-weather predictive capability. In particular, we draw upon the recently completed Data-Optimized-ICME-Modeling database of thousands of simulated CMEs propagating and evolving in the solar wind, which is based on the combined Wang-Sheeley-Arge (ADAPT), Gibson-Low, and Gamera models. This database offers a powerful new means of studying the correlation between different CME characteristics and an avenue for deeper study of the physical causes of these correlations.
