Dear authors,

I accept your paper for publication in GMD. Only a few corrections should still be made, as follows:
Sect. 3.2.1, tst par, line 4: the deleted "one" should re-appear, i.e. "the one implemented in...".
Eq. 5, upper limit of first integral sign: make font of lower index v consistent with other appearances of r_v.
Sect. 3.1.3, 1st and 2nd par: either "Kessler's scheme" (without "the") or "the Kessler scheme".
Sect. 5.1, and 5.1.1: replace "water solution" with "aqueous solution" or simply with "solution".
At the same place, I would also prefer the order of the arguments turned around, because it puzzled me that the assumption of spherical drops seemed to be in conflict with assumptions about the relative humidity. I think writing: "all particles composed of aqueous solution and spherically shaped" would solve this minor problem.
Last line of sect. 5.1.5: should probably be "section 5.1.3. (?).
Section 5.1.6, line 7: delete everything after "computational particles" (density per cell makes no sense).
End of the paper: the reference to the supplement appears twice, after the main text and again after the appendices.
Reply to review of 21 January 2015 concerning formulation of sedimentation: I feel no necessity to display these equations in section 4.1.4. Leave it as it is.
