Abstract
Omnidirectional electron fluxes measured by the Medium Energy Particle Instrument (D.J. Williams, APL/JHU) flown on the ISEE-1 satellite, are used to quantify the near earth electron environment. Data from a magnetometer (C.T. Russell, IGPP/UCLA) flown on the same spacecraft are also used to assess the validity of the magnetic field models employed to map the spacecraft orbit into geomagnetic B and L coordinates.
Average fluxes in B and L cells covered by the ISEE-1 orbit are compared with the AE8 data set, the standard NASA model for trapped electrons. At low altitudes, the two data sets agree qualitatively; at higher altitudes, the MEPI data imply that the AE8 fluxes fall off too quickly.
