Abstract
Instrumentation under construction and testing at the NOAA Aeronomy Laboratory for conducting measurements of the zenith sky and the moon in order to measure molecular abundances of trace gases in the stratosphere at extremely low levels of absorption (less than 0.05 percent) is discussed. The instrumentation consists of a telescope (for lunar observation at night or direct sun during the day), a light feed, a spectrograph, an array detector, and a data analysis system. The telescope design is a dual off-axis parabolic feed with polarizers, depolarizers, image rotators, and other optical modifiers that can be inserted at the feed focus to test their effect on the residual spectrum. The spectrograph is a cast aluminum 3/8-m f/6 double crossed Czerny-Turner system.
