GCS-Benchmarking

Coronal Mass Ejections (CMEs) are immense clouds of charged particles emitted from the sun. When a CME reaches Earth or a spacecraft, it can negatively affect power grids, electronics, radio communications and GPS.

Predicting where a CME will arrive and the severity of its impact can help offset these effects. Several models exist to simulate CME propagation thoughout the solar system, but there is currently no common set of simulation input parameters. This makes it challenging to determine whether a given model’s performance is due to its CME input parameters or its model settings.

To aid in solving this problem we have created eUCLID: the Universal CME modeL Input Dataset. This catalogue of historical CME parameter measurements is intended to be used as inputs to CME propagation models in validation efforts.
