Suggestions for revision or reasons for rejection

The manuscript has been revised thoroughly well according to the reviewer’s comments and become more scientifically focused than before. However, there still are several sentences not easy to understand their meaning properly which will require further English editing. Furthermore, there are several sentences which describe a figure or table, but it is not clear which part of figure or table they are describing. I strongly recommend the authors to check all such descriptions and revise them if necessary. One example of such description is in the line 267 starting from “The increase of PM2.5…”. I could not understand which part of the Figure 5 you want to describe. There still are such unclear descriptions which greatly deteriorate the readability of the manuscript. Another big concern is that the introduction section is still long and redundant. It’s good to have a thorough review of the background, but it should cite only indispensable papers. Followings are specific points for further revision.

-L121: What does “integrated emissions” mean?

-L139: Why “therefore” here?

-L172: MIX inventory is not only for China

-L174-176: Did you do this adjustment for MIX emission in entire model domain?

-Table1: Which scenario did you use for this table? This kind of basic information should be described in the table caption or manuscript. Temporal resolution of the observation should be described somewhere in the manuscript. The same comments go to Table2.

-L192-193: Does this sentence describe only for July case?

-L219: How did you estimate these values of the contributions of local pollution?

-Figure 2: Figure caption should state that these figures show the difference between Base case and the other sensitivity simulation case for the sake of clarity. The term “impact” is not so clearly describing what you show here.

-Figure 3: The same indications for Figure2 above. Furthermore, the Y-axis of Fig 3 should be delta(concentration).

-L226: The “relative” impact was..

-L239: 2(f)) --> 2(f)

-L266: appeal --> appear?

-L275-276: Fig5(c-2) and Fig5(c-3) should be switched.

-L276-277: Is this consistent with the fact that CLD is the main production process in Fig5(d-4)?

-L281: What is the “north” here?

-L299: What does “the lower 20 averaged layers” mean here? Does Figure 5 show the daily process contributions averaged in the lower 20 layers? If so, you must clearly state it in the figure caption and/or in somewhere in the manuscript.

-L310: This is not always true. Could you specify when and where this statement is true?

-L331: What does “nonuniform” mean here? What do you want to mean?

-L382: Fig S4.12 --> Fig S4.11?

-Figure 5, 8. 9: BR --> BQ

-Figure 11: #17, 18, 19, 20 should be modified.

-L445: overestimated <--> underestimated

Short summary

This study evaluated the impact of Asian haze from the three biggest industrial regions on Taiwan and analyzed the process during transport. The production and removal process revealed the mechanisms of long-range transport. This is the first time that the brute force method and process analysis technique has been applied in a Community Multiscale Air Quality Modeling System. Also, this study simulated the interesting transboundary transport of pollutants from southern mainland China to Taiwan.
