Climate & Space Professor Tamas Gombosi and a team of U-M researchers have a developed a new tool that will help forecasters better predict the intensity and emission paths of solar coronal mass ejections, or CMEs.

CMEs are eruptions from the sun’s corona, or upper atmosphere, that spew plasma and magnetic energy into space. These enormous clouds of magnetically charged particles have been historically difficult to predict, and can cause widespread disruptions to the Earth’s magnetic field, electronic communications, and power grids.

The new tool is called EEGGL (“eagle”) and stands for Eruptive Event Generator (Gibson and Low). Designed to simulate solar storms, EEGGL helps track the path of CMEs and determine the shape and scope of the event before it collides with the Earth’s magnetosphere. 

EEGGL is a component of the larger Space Weather Modeling Framework that was developed by Professor Gombosi and his team, and was adopted by NOAA’s Space Weather Prediction Center this past October. The tool itself is hosted by the Community Coordinated Modeling Center, or CCMC, at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
