摘要：
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(Q5) branch of the rotational-torsional spectrum, with some confirmation from the 94 cm-1 R(Q4) branch. The atmospheric spectra were obtained from a balloon flight on September 26-27, 1989, launched from Fort Summer, NM. The volume mixing ratio of H2O2 is 1.6 x 10(-10) at 38.4 km, decreasing to 0.6 x 10(-10) at 23.8 km, with uncertainities of about 16% (1-sigma). Our measurements are compared to a recent stratospheric model calculation.
