Infrared spectra of Venus produced by a Fourier spectrometer flown aboard the NASA CV 990 jet aircraft were analyzed for water-vapor content by comparison with calculated model spectra. The reflecting layer model gave an abundance of 1.6 ± 0.4 μ of precipitable water for the two-way transmission of the Venus atmosphere. The scattering model resulted in a value of 0.25 ± 0.10 μ of water per scattering mean free path. Neither is regarded as a definitive model, but derived mixing ratios will not be significantly in error. An abundance of CO2 using an number of bands in our region was determined for both models. The volume mixing ratios of H2O to CO2 obtained were 0.6 × 10-6 and 1.0 × 10-6 for the reflecting layer and scattering model, respectively.
