The stratospheric vertical distribution of CO is obtained from balloon-based FIR limb thermal emission spectra by analyzing several limb sequences of the R8 and R1 spectral lines at 34.588 and 49.932/cm, respectively. This constitutes the first determination of the stratospheric CO profile from IR thermal emission spectra. The results, indicating 24.6 + or - 7.6 ppbv at 21 km and 34.4 + or - 10.1 ppbv at 37 km, are compared with the remote-sensing and in situ measurements by other groups and with photochemical-dynamical model calculations. |
