Suggestions for revision or reasons for rejection

This manuscript has improved considerably from the previous version. It requires still some improvements before I can recommend acceptance for publication.

Section 1.
The points 2 and 3 on lines 6-8 overlap each other. All the ways by which aerosol particles influence cloud properties (albedo, precipitating properties, cloud radiative properties) originate somehow from the fact that aerosols act as cloud condensation nuclei (or ice nuclei). Please combine these two points or modify.
Line 28 in page 5: Rather “Mt Tai is optimal…” than “It is optimal…”
Check out the use of tense here and elsewhere (e.g. “are” on line 51 in page 5 vs. “were” on line 2 in page 6)

Section 3.2
Lines 8-9: I would delete the sentence “The majorities of particle mass…”. This tends to be the case almost everywhere in the troposphere, so no need to state.
Line 11: Maybe a new paragraph could be started from “Seasonally, maximum…”

Section 3.3.1
Line 47 on page 10: Figure 3 rather than Figure4?
Line 14 on page 11: “Atmospheric new particle formation “ rather than “Atmospheric formation”

Section 3.3.2
Please do not use ackronym in section title, but instead write “Mass size distributions of chemical…”
Please use consistently the terms “polluted episodes” and “NPF events” throughout the text in this section when referring to those cases. Using just the words “polluted” or “NPF” in this context causes confusion.
Another term that causes confusion here (and in section 4) is “increasing factor”. I would suggest defining this explicitly, e.g. “the ratio in the value of MMD between the polluted episodes and NPF event”.

Finally, the language of this manuscript should be carefully checked out.

Short summary

An AMS was employed to measure the mass and size distributions of PM1 at an elevated site. Features of PM1 at four seasons, during different kinds of episodes including NPF, polluted, PBL, LFT and in-cloud, were discussed. The characterizations of PM1 at seven clusters of air masses were also analyzed. BBOA, CCOA and oxidized organic aerosols were resolved by AMS-PMF (positive matrix function). Almost half of OA were oxidized, and BBOA is 34% of OA in summer; CCOA is 22% of OA in winter as well.
