We report temperatures in Venus' upper mesosphere/ lower thermosphere, deduced from analyzing very high resolution infrared spectroscopy of CO2 emission lines acquired in 1990, 1991 and 2009. Kinetic temperatures at 110 km altitude (0.15 Pa) are derived from the Doppler width of fully-resolved single line profiles measured near 10.4 μm wavelength. Venus was close to inferior conjunction in all observations. Measured temperatures range from 200 - 240 K with uncertainty typically less than 10 K. Comparisons are made to Temperatures retrieved more recently from the SOIR instrument on Venus EXpress and from ground-based sub-mm retrievals. Temperature variability appears to be high on day-to-day as well as longer timescales.
