a A sketch of the MPL and RRM lidar beams along the north–south axis. At the altitude of 6.2 km AGL (~ 6.6 km ASL), the two instruments detected the mean altitude of the KH billows at a horizontal distance of ~ 3.1 km. b The corresponding sketch in the horizontal plane. The KH billow axis was obtained from the fish-eye camera photographs (Fig. 12). According to the wind measurements taken by the MU radar, the RRM lidar detected the same KH billows as MPL about 71–77 s later (but not at the same location along the billow axis). It is consistent with the time correction applied in Fig. 7
