Abstract :
The OGO-IV ultraviolet airglow spectrometer, which measures the earth´s spectrum between 1100 and 3400 Ã…, consists of an Ebert-Fastie monochromator and two photomultipliers with wide-dynamic range electronics. The cesium telluride photomultiplier channel measures the backscattered ultraviolet daylight between 1750 and 3400 Ã… over a dynamic range of 10 with a spectral resolution of 20 Ã…. The cesium iodide photomultiplier channel measures air-glow emission lines between 1100 and 1750 Ã…, even with the fully illuminated earth for a background.
