Add to ORKGAuthor Institution: Harvard-Smithsonian Center for AstrophysicsAltitude profiles of the concentrations, and their diurnal variation, have been measured for stratrospheric OH and $HO_{2}$, as well as $H_{2}O_{2}$ and a number of related atmospheric trace species. The measurements are made from far infrared thermal emission, using a Fourier transform spectrometer on a high altitude balloon platform. Results of the measurements and analysis for $OH, HO_{2}$ and $H_{2}O_{2}$ using balloon-borne measurements from 36 km, obtained in the fall of 1989, are presented here. The underlying spectroscopy necessary for the identification and quantitative analysis of these species is discussed in detail
