Fig. 19From: Evaluation of a method to retrieve temperature and wind velocity profiles of the Venusian nightside mesosphere from mid-infrared CO2 absorption line observed by heterodyne spectroscopyRetrieved wind velocity profiles at a 33SLT3 and b 67NLT0. Blue cross lines show the retrieved results with their errors (horizontal) and vertical resolutions (vertical), shown in Fig. 18. Black solid lines are the wind velocity profiles deduced by a GCM study from Gilli et al. (2017). Black dashed lines in a show the model value obtained in Alexander (1992). The zonal and meridional wind velocities are converted to the wind velocities along the line-of-sight of the observing geometriesBack to article page
