The radiation belts consist of energetic charged particles trapped by the Earths magnetic field which consists of an internal field and an external field. The external field dominates the non-dipole portions of the internal field at and above geosynchronous altitude. External field modeling usually begins with models of the various current systems from which the field is derived. CRRES data provides for a generation of new models of the radiation belts. A Strawman proposal was developed for the CRRES static radiation belt model Product Associated Data Base. Several groups of models were studied in preparation for working with the CRRES data. The models and software to run them constitute a suite of routines divided into five categories. A B sub MIN survey data base was constructed to study the effects of magnetic latitude and local time at B sub MIN. The behavior of the PROTEL instrument on CRRES was modeled in its hostile environment to evaluate its performance. Predictions of the developed Contamination Code compared very well with the results from the Harvard Cyclotron experiments. The CRRES Dosimeters were modeled for an isotropic, a mirror plane and the sin N alpha pitch angle distributions.
