This well-written study shows that the seeding agent in hygroscopic flares can be detected in the cloud droplets, and related to the indicated changes in cloud microstructure.

The indicated effect of the flares in the limited sample is mainly the tail effect of the largest particles initiating large cloud drops and drizzle. These results do not support the competition effect, although much more data is required for conclusive evidence. I encourage the authors to add such a statement in their conclusions.

There are several minor comments:

Line 31: Change “inclusive” to “elusive”.

Figure 6b and c; Fig 7b and c: It is impossible to separate the SCl and NSCl cloud segments. If the yellow points are considered NSCl, please state so explicitly and justify it.
