A balloon-borne resonance fluorescence instrument for in-situ measurement of atomic oxygen (O(3P)) was developed and its performance was characterized based upon numerical simulations and laboratory tests. A simultaneous measurement of O(3P) and ozone (O3) in the upper stratosphere was carried out onboard a high altitude balloon launched from Sanriku (39°N, 142°E), Japan on 9 September 1997. O3 was measured on the same balloon by the solar UV absorption technique. The measured density ratios [O(3P)]/[O3] at altitudes 38–44 km were found to be consistent with the calculated within the experimental uncertainties, although a systematic discrepancy was found above 41 km. It was difficult to make a detailed discussion about this discrepancy due to the insufficient precision and accuracy.
