Strong 10 micrometer line emission from /sup 12/C/sup 16/0/sup 2/ in the upper atmosphere of Venus was detected by heterodyne techniques. Observations of the absolute Doppler shift of the emission features indicate mean zonal wind velocities less than 10 m/s in the upper atmosphere near the equator. No evidence was found of the 100 m/s wind velocity implied by the apparent 4-day rotation period of ultraviolet cloud features. (auth)
