From: 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 spectroscopy

Fig. 8

Statistical results for a, b the retrieved temperatures and c, d wind velocities from the model spectra with 41 wind velocity profiles of − 200 to + 200 m/s at all altitudes and white noise with the RMS of 1.0 erg/s/cm2/sr/cm−1. The cold case results are shown in a and c, and the warm case results are shown in b and d. In the right panels of a–d, red lines are the mean differences between the retrieved and model profiles, gray areas are the standard deviations of the differences, and blue dashed lines are the mean retrieval errors. Left panels a–d show the same AKs in Figs. 6a, b, 7a, and b, respectively, as examples
