Popis: The CRRES Magnetospheric Ion Composition Sensor (MICS) was used to obtain the relative oxygen charge state abundances in the earth’s inner magnetosphere (3 +3 on average. As expected, O+ is the dominant oxygen ion at all times in the inner magnetosphere for energies >60 keV/Q. During average conditions the Q≥+4 ions have fluxes comparable to O+3 in the L=4.5–7.5 region and are about 50% of the O+3 fluxes in the L=3–5 regions. Thus, the average O+3 fluxes appear to represent a transition state between ionospheric and solar wind source oxygen.
