Recent aircraft and balloon borne measurements of OH and HO{sub 2} are reviewed. The authors demonstrate the ability of the laser-induced fluorescence technique to provide accurate, high signal to noise ratio measurements of OH throughout the upper troposphere and stratosphere. HO{sub 2} is measured as OH after gas phase chemical titration with nitric oxide. The addition of the HO{sub x} measurement capability to the suite of instruments aboard the NASA ER-2 aircraft has provided a wealth of new information about the processes that determine the concentration of ozone in the lower stratosphere. These simultaneous, in situ measurements provide a unique test of present understanding of the mechanisms that control the odd-hydrogen chemistry of the lower atmosphere. 17 refs., 8 figs., 1 tab.
