Notes. The latitude range intervals are the same as in Ando et al. (2020). Values for N are obtained using the equations inSect. 3.3 and the temperature profiles obtained from radio occultation data from Akatasuki, described in Ando et al. (2020). We present the value and its propagated error for each entry. For
and k we present its range of values (minimum and maximum) across both VIRTIS and IR2 datasets and the mean velocity error and propagated error for the wave number across all measurements. For the wind shear and its variability we present the mean within the largest altitude range described earlier (44–56 km) along with its standard deviation across all latitude ranges as all values are within the presented error.
