The authors introduce the first 3D wind measurements up to the stratosphere based on an updated version of their VAHCOLI system. In particular, they extended the system by multiple telescopes that enable the simultaneous measurements of 4 LOS directions (N, S, W, E) as well as the vertical component. They demonstrate the functionality of the system based on an exemplary measurement and comparison to both ECMWF data as well as Aeolus data. The paper is well-structured and clearly understandable. Still, a few important pieces of information to interpret the presented results are missing. Furthermore, a few of the drawn conclusions are questionable. Hence, I recommend accepting the paper for publication in AMT after major revisions based on the comments that are listed below.

In the introduction, the importance of wind field measurement, the methods of wind field measurement and the shortcomings of various methods are introduced in detail, which leads to the development progress of coherent lidar. And explains the reasons why spaceborne lidar need to use both Mie and Rayleigh lidar, thus leading to the technical progressiveness of this manuscript. Shows the capable of detecting Mie signals that better than ALADIN.

In line 115, the angle correction methods is very good, effectively avoiding wind field errors caused by angle deviation.

In line 145, ‘For data processing the individual pulse raw dat…’, seems syntax error.

Above 150, eight resolution of 1 m for each individual field of view. What is the width of the laser pulse?

In line 205, obviously, it can be used to correct ECMWF, but the transmission of gravity waves above 11km is only a guess, and a simple wavelet analysis can be done for simple analysis.

In figure 11. The satellite and lidar are several tens of kilometers apart, and this comparison result is still very good, can you explain the reason?
