We have made the first unequivocal measurement of hydrogen peroxide in the stratosphere, a concentration profile obtained from a balloon platform using Fourier transform thermal emission spectroscopy in the far infrared. Measurements were made using the 112 cm −1 R Q 5 branch of the rotational‐torsional spectrum, with some confirmation from the 94 cm −1 R Q 4 branch. The atmospheric spectra were obtained from a balloon flight on September 26–27, 1989, launched from Fort Sumner, NM.The volume mixing ratio of H 2 O 2 is 1.6 × l0 −10 at 38.4 km, decreasing to 0.6 × l0 −10 at 23.8km, with uncertainties of about 16% (1σ). Our measurements are compared to a recent stratospheric model calculation.
