Suggestions for revision or reasons for rejection

The authors were very responsive and have done a lot of work to address the concerns from the reviewers. All my major questions and concerns have been well addressed in details. The paper has been significantly improved and I recommend acceptance for publication after some minor/technical revisions/corrections. Note that there are still a lot of grammar errors or typos and I may not be able to identify all of them. A thorough editing is still required.
Minor suggestions or technical corrections:
1. Abstract: Since the title mentions about the severe haze pollution, it should be identified in the abstract that the evaluation was done for haze cases.

2. Lines 19-21, “The pollutants prediction by atmosphere chemical model exist obvious deficiencies, which may be closely related to the uncertainties of the momentum and sensible heat fluxes calculated in the surface layer”: Here “prediction”, not “pollutants”, is a singular subject and hence a singular verb “exists” should be used.

3. Line 26, “the algorithms of universal functions”: universal functions for what? surface fluxes? Please specify.

4. Lines 60-61, “Many international scholars verified the MOST using of field experiments”: Do the authors mean “Many international scholars verified the MOST using field experiments”?

5. Line 75, “have” should be “has”.

6. Lines 80-82, “The observed momentum and sensible heat flux data covering once complete haze process at Gucheng station was used to evalute the two schemes focsuing on the transition stage from unstable to stable atmospheric stratification corresponding to the PM2.5 accumulation”: “once” should be “one”; “was”: should be “were”; “evaluate” should be “evaluate”; “focsuing” should be “focusing”.

7. Lines 90-91: The period “.” after the equation should be a comma “,”, and “Where” should not be capitalized. Check all the other equations in which “where” is used.

8. Line 92: A comma “,” needs to be added in front of “respectively”.

9. Line 93: The subject “they” can be omitted.

10. Line 99: do the authors mean “from at least two levels”?

11. Line 101: “employ” should be “employs”.

12. Line 112: should “universe” be “universal”?

13. Line 183: add “were” before “measured”.

14. Section 3: It is my understanding that this study focuses on the impact of the surface flux parameterization on air pollution modeling. Therefore, the haze pollution case(s) or episode(s) should also be briefly described in this section.

15. Line 370: “results in” should be “result in”.

Short summary

Two surface layer schemes are evaluated in eastern China based on observational flux data. The results indicate that the Li scheme better describes regional atmosphere stratification compared with the MM5 scheme, especially for the transition stage from unstable to stable atmosphere conditions, corresponding to PM_2.5 accumulation. Our research suggests the potential improved possibilities for severe haze prediction in eastern China by coupling Li online into atmosphere chemical models.
