Three in situ, midlatitude, midday observations of HO2 in the earth's stratosphere are made using a chemical conversion-resonance fluorescence technique. The mean of the observed HO2 volume mixing ratios are given for altitudes of 37, 35, 33, 31, and 29 km with significant variability observed among the three observations. The results are compared with a recent model of stratospheric chemistry. It is shown that while the calculated distribution falls within the band defined by the observations, the mean of the observations lies consistently above the calculations, though never by more than a factor of two. A comparison between the rate of odd oxygen production by O2 photolysis and the rate of HOx catalyzed destruction demonstrates that hydrogen-oxygen free radicals account directly for a fractional destruction of Ox between 5 and 10% in the altitude interval between 29 and 37 km given current formulations of stratospheric chemistry.
