Abstract
Using a simple photochemical model we derive the mixing ratio profile of ClO in the altitude range 20-38 km from simultaneous measurements o f HO2, OH, HOCl, temperature, pressure, and ozone. The measurements we re made with the FIRS-2 far-infrared spectrometer during a balloon fli ght on September 29, 1992. We compare the derived ClO with the ClO pro file obtained by the SLS instrument while flying on the same gondola. The good agreement between the two profiles validates our simple model and confirms the relevant rate constants and photolysis cross section s.
