Although the reviewers commended some improvements in the manuscript, still essential points for clarification remain, which have not been addressed appropriately. Please carefully address all remaining points from the two reviewers.

The last concerns of the reviewers have been addressed and the manuscript is suitable for AMT publication. Nevertheless, one point remains questionable, which is related to the correlation of the zonal and meridional winds for ERA-interim and the MST radar. Note that a correlation is large when the dynamic range of the correlated variable is large with respect to the difference in the variable. Note also that the dynamic range of the zonal wind is much larger than that of the meridional wind (Fig. 10). This leaves the question whether the difference in correlation between zonal and meridional wind is related to the different dynamic ranges or to larger differences in the meridional wind (in m/s). The latter is most relevant for the MST radar validation. Please clarify by presenting difference statistics (e.g., SD, RMS, or MAD) for this data set.

Thanks for your final corrections!
