To better understand these changes in the South Atlantic Anomaly, NASA researchers worked with several other institutions to model 125 years of the anomaly. To do this, they used NASA’s in-house Geomagnetic Ensemble Forecasting System, running a 512-member ensemble simulation ranging from 1900 to 2025. The simulations were powered by the Blue Waters supercomputer at the National Center for Supercomputing Applications, which completed all of the massive simulations in a matter of weeks.
