Fig. 3From: 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 from the model spectrum generated from temperature of VIRAex and wind velocity of 0 m/s (green line in Fig. 1). Colored lines show the profiles retrieved with 41 a priori wind velocity profiles (red: positive wind velocity, blue: negative wind velocity). Black dashed line shows the standard deviation for these profilesBack to article page
