I thank the authors for the generally comprehensive responses to reviewer comments.

In the instance where a reviewer became confused about the usage of "droplet" to refer to unactivated aerosol and no revision was yet made: I can understand their confusion and agree that "particle" may be in wider use to span aerosol and hydrometeor categories (e.g., Jacobson, 2005). To avoid similar confusion for other readers, and since the terms "aerosol", "CCN", and "particle" are all used as well, please clarify how you will be using the term "droplet" at first use in that dual capacity. I believe that may be where the Köhler equation is introduced. A possible clarification could be as follows: "We hereafter refer to the spherical particle as a droplet, regardless of whether it is at equilibrium with water vapor (as a CCN) or activated (as a cloud droplet)." or something of that nature. Thank you in advance for making that clarification. Such terminology confusion could be an indicator of education primarily in the aerosol or cloud community.

On a second reading of the brief review of relevant physics, I suggest to include a reference regarding homogeneous nucleation for the interested reader. With such a reference, a more precise statement could be "In an Earth atmosphere without aerosol particles, droplet formation rates would remain vanishingly weak (e.g., Wyslouzil and Wölk, 2016)." I defer, but suggest that readers interested in that underlying physics could appreciate to see a reference for further reading.
