Abstract:

Space systems planners--space engineers as well as physicists--require for their work accurate values of the fluxes and energy spectra of protons and electrons trapped in the geomagnetic field. Numerous measurements have been made of the Van Allen belt radiations on many satellites, with different instruments and at different times. Most of the experimenters organize their data in terms of McIlwains B, L coordinates, but intercomparison of the results from different experiments is still complicated by temporal variations of the fluxes and differences in energy response of the various instruments used to obtain the data. A need existed, therefore, for collating the individual measurements and for constructing a model environment. In the NASA report SP-3024, Volume I, AD-659 722 a description was published of the inner radiation belt. The purpose of this report Volume II is to update the electron environment in the inner belt and to extend it out to L 6. In addition, codes have been developed for integrating the flux along satellite orbits.
