High‐energy outer radiation belt dynamic modeling

Specification of the average high‐energy radiation belt environment in terms of phenomenological montages of satellite measurements has been available for some time. However, for many reasons both scientific and applicational (including concerns for a better understanding of the high‐energy radiatino background in space), it is desirable to model the dynamic response of the high‐energy radiation belts to sources, to losses, and to geomagnetic activity. Indeed, in the outer electron belt, this is the only mode of modeling that can handle the large intensity fluctuations. Anticipating the dynamic modeling objective of the upcoming Combined Release and Radiation Effects Satellite (CRRES) program, we have undertaken to initiate the study of the various essential elements in constructing a dynamic radiation belt model based on interpretation of satellite data according to simultaneous radial and pitch‐angle diffusion theory. In order to prepare for the dynamic radiation belt modeling based on a large data set ...
