Laser heterodyne spectroscopyHigh-resolution heterodyne spectroscopic studies of the atmosphere of Venus are surveyed with attention to Doppler shifts in the 10-micron CO2 lines. While the C-12(O-16)2 emission lines formed in the mesosphere near 115 km indicate that the winds are distinctly subsolar to antisolar, C-13(O-16)2 absorption lines for the stratosphere at about 75 km confirm that the pattern is a strong retrograde rotation with an average equatorial velocity of 90 plus or minus 7 m/sec. It is concluded that the winds change from retrograde to subsolar-to-antipolar between 80 and 115 km.
