Abstract Fourier spectrometers for the investigation of infrared spectra of Venus were installed on the recent Soviet orbiters “Venera-15” and “Venera-16”. Many spectra with reliable absolute calibration were obtained in the 280–1500 cm−1 region with a spectral resolution of 5 cm−1 (ground based processing) and about 7 cm−1 (preoprocessed on board) and a spatial resolution of about 100 km at the Venusian cloud top level. Bands of CO2, H2O, H2SO4 and SO2 are identified. The 15 μm-CO2- fundamental band was used for retrieval of altitude dependent temperature profiles. There are significant differences in the cloud structure above 60 km for distinct regions of Venus, demonstrated by differences in the spectra.
