The revised version of the manuscript addresses most of the referee comments in sufficient detail. There are a few, mostly technical issues that should be considered before the paper can be considered ready for publication.

Referring to the first comment by referee 1, the multiplication factor in calculating CS should indeed be 2πD, not 4πD as in equation 1 or incorrectly given in Kulmala et al. 2012. Note that in the original paper by Kulmala et al. 2001 which introduced CS, there is 4πD but that is multiplied by the particle radius, not diameter as currently in practice. Unfortunately, this has caused plenty of confusion during recent years. I would encourage the authors to correct this point: at the end it has little influence on the actual results, affecting mainly the absolute values of reported CS.

In general, the paper is very clearly written and with a proper language. However, the following should be checked out: 1) in many places it reads "between M-N" although it should be either “between M and N” or "in the range of M-N", 2) in some of the new text, articles seems to be missing, 3) the text in section 2.4 requires some improvements, please check out.

The term "high ozone" does sound scientifically correct, should it rather be "high ozone concentration"?

On lines 391-392 in the file marked by track changes, should one write "…with an increasing temperature"?

The information in Yan et al (2018) in the reference list seems to be incomplete. Please correct.

The re-revised paper is acceptable for publication in its present form.
