The authors have responded most of the referee comments. However, when looking at the revised paper, there are still a few issues that should be considered before accepting this paper for publication. They are listed below.

In the introduction the authors discuss marine aerosols in very general terms, but then mention emission trends that are not true in general in the global atmosphere (lines 97-100). Please either mention explicitly here that you refer to Asian emissions, or revise the text according to what has taken place in different continents (In Europe and NA, for example, SO2 emissions have decreased for several decades and also NOx emissions have evolved very differently from those in Asia).

line 161: Surface tension is a composition-dependent variable, not a constant. It is usually set constant when applying the equation to calculate the hygroscopicity parameter cappa, but that is a different thing. Please correct the text.

Lines 362-369: The minimum diameter of particles at SS of 0.2-1 % is somewhere in the range 50-100 nm, so statement about nanometer-size particles on lines 366-367 is very confusing. Why to talk about nanometer-size (sub-10 nm) particles here? Is this statement even correct? There is often more organics in sub-100 nm particle compared with accumulation mode particles, but the situation in the sub-10 nm size range may be totally different. Please be more careful here what size ranges you are really referring to here.

Section 3.6, end of Introduction and Figure 7: I would recommend using the terms "relationship" or "regression equation" rather than "correlation" here. The term "correlation equation" does not sound correct at all.

The text still contains many grammatical problems (lack of articles, wrong prepositions etc.). Please check out the text once more with the help of a native English speaker.

The authors have addressed the minor remaining comments in a sufficient detail. The manuscript is now acceptable for publication.
