ZCB This composite image is produced from GUVI radiance data (Level 1C) plotted as a strip image for a complete day. It is a composite of the O I 130.4 nm emission (blue), O I 135.6 nm (green), and LBH Short (140 - 150 nm) (red). White typically indicates dayglow emission, green indicates nightside recombination emission, white streaks typically indicate stars in the instrument field-of-view. The GUVI data used here are provided through support from the NASA MOamp;DA program. The GUVI instrument was designed and built by The Aerospace Corporation and The Johns Hopkins University. The Principal Investigator is Dr. Andrew B. Christensen and the Chief Scientist and co-PI is Dr. Larry J. Paxton. See also Data Usage Policy at http://guvitimed.jhuapl.edu/home_guvi-datausage.
