Abstract : Temporal variations in the trapped natural electron flux intensities and energy spectra are discussed and demonstrated using recent satellite data. These data are intended to aquaint the space systems engineer with the types of natural variations that may be encountered during a mission and to augment the models of the electron environment currently being used in space system design and orbit selection. These models, while excellent in some respects and quite satisfactory in most other respects, were generated before high resolution spectrometry data were generally available. (Author)
