We will examine compositional changes in the near-Earth neutral H and O emissions detected with the Low and High Energy Neutral Atom imagers (LENA and HENA) aboard the Imager for Magnetosphere-to-Aurora Global Exploration (IMAGE) satellite during magnetic storm periods in 2001. In comparison with in situ ion composition measurements from the CLUSTER Ion Spectrometry (CIS) experiment on three of the CLUSTER spacecraft, remote neutral atom measurements from IMAGE will be used to probe the global behavior of upflowing and ring current ions, whose interaction with the neutral H geocorona produces energetic neutral atoms. By analyzing temporal and spatial variations in the composition of neutral atoms measured with LENA that are associated with upflowing ions, ring current ions deduced from HENA data, and direct ion observations from CIS, and by making comparisons between individual storm periods, we will investigate the possible transport of upflowing ionospheric ions to the ring current region.
