Abstract

The GLO experiment includes a ground-controlled shuttle- based UV-vis-IR spectrograph and imager set, and has flown on four space shuttle flights, including three in 1995. Each flight returned limb-view on metal atom and ion emissions in the 80-350 km tangent height region. Improved optics provided 0.3 nm FWHM resolution in the ultraviolet, and simultaneous altitude profiles were routinely measured that spanned 150 km in tangent height with 10-15 km resolution. CLouds of metal ions, particularly Mg⁺, were observed in daytime above 120 km tangent height near the geomagnetic equator. The GLO project returned approximately 30 gigabytes of spectral data in 1995. The current high altitude metal ion emission measurements are reported here.
