AB: By using a 630 nm filter, airglow emissions in 60-250 km range were measured by the FORMOSAT-2 satellite using the ISUAL instrument (Imager of Sprites and Upper Atmospheric Lightning ). Measurements in Oct 2004 and March-April 2007 revealed two layers of airglow produced by OH and O(1D). The emissions of O(1D) and OH had maximum intensity in the equatorial regions, but with maximum latitude varied from day to day. The OH intensity showed an oscillation of two day period, but O(1D) varied by many factors. By comparing the relative intensity and height separation of these two airglow layers, we found the intensity of O(1D) was generally stronger than OH in the southern hemisphere but weaker or comparable with OH in the northern hemisphere.
