What is it about?

This paper describes a model that we developed in order to predict hazards to satellites from the Earth's Van Allen Radiation Belts. The model uses data assimilation techniques. Data assimilation combines physics-based numerical models with satellite observations to give more accurate predictions.

Why is it important?

The DREAM model has been used in a number of important scientific publications focused on better understanding of the Earth's radiation belts and is now in testing at the NOAA Space Weather Prediction Center.


This is the go-to paper for understanding how the DREAM model is put together. It also provides some of the initial validation and testing results.
