Built to simulate solar storms, EEGGL helps NASA study how a CME might travel through space to Earth and what magnetic configuration it will have when it arrives. The model is hosted by the Community Coordinated Modelling Center (CCMC). It returns a series of synthetic images, which look similar to those produced of actual observations from the SOHO and STEREO spacecraft. By taking into account the magnetic structure of a CME from its initiation at the Sun, we will have a better idea of how this structure influences its path through space and interaction with Earth’s magnetic fields – an important piece to the puzzle of the Sun’s dynamic behaviour.
A team led by Tamas Gombosi at the University of Michigan's Department of Climate and Space Sciences and Engineering developed the model as part of its Space Weather Modelling Framework, which is also hosted at the CCMC. All of the CCMC’s space weather models are available for use and study by researchers and the public through runs on request. In addition, EEGGL, and the model it supports, is the first of the “first principles” model to simulate CMEs including their magnetic structure open to the public.
