First Multi-Decade Simulation of the Earth’s Radiation Belt

A new simulation of the Earth’s electron radiation belts captures large-scale variations over nearly three solar cycles, and replicates primary cyclical features and extreme behaviors.

Radiation belts pose internal charging and total dose hazards to satellites. The climatological mean and extreme environments represent critical spacecraft design parameters. Glauert et al. [2018] present a long-term, multi-Solar cycle simulation of the radiation belts. Because satellite designers must generally account for risks associated with a credible worst case Solar cycle, this kind of long simulation represents a first attempt by the scientific community to use a physical simulation to address that risk. Many challenges remain, but the paper nonetheless marks an important milestone on the road from scientific capability to end user need.
