Abstract : This technical report documents the software package CRRESELE. CRRESELE utilizes electron radiation belt models constructed from data measured by the High Energy Electron Fluxmeter (HEEF) flown on the Combined Release and Radiation Effects Satellite (CRRES). CRRES flew in a geosynchronous transfer orbit for 14 months during solar maximum. The electron models are omnidirectional flux maps binned in L shell and B/B0 (azimuthal symmetry is assumed) for a given energy. The CRRESELE utility calculates electron omnidirectional fluences (differential and integral) for 10 energy intervals (0.5-6.60 MeV). A user specified orbit is traced through eight different outer zone electron flux models, at each energy, to provide an estimate of electron fluences received by a satellite under a wide range of magnetospheric conditions. Six of the eight CRRESELE models are parameterized by geomagnetic activity, the seventh is simply a mission average, and the eighth is constructed from maximum flux values, caution must be used when interpreting the results because CRRESELE is restricted to modeling the outer zone electrons from L=2.5-6.5, and consequently, excludes any electron fluence contributions from the inner zone and slot region.
