A stratospheric ozone absorption line in the 10 µm band has been measured and resolved completely, using an infrared heterodyne spectrometer with a spectral resolution of 5 MHz (0.000167 cm −1 ). The vertical concentration profile of stratospheric ozone is obtained through an analytical inversion of the measured spectral line profile. The absolute total column density was 0.32 ± 0.02 cm‐atm with a peak mixing ratio occurring at ∼ 24 km. The (7,1,6) ‐ (7,1,7) O 3 line center frequency was found to be 1043.1772 ± 0.00033 cm −1 , or 420 ± 10 MHz higher than the P(24) CO 2 laser line frequency.
