Dear Editor and Reviewers,

The authors presented their efforts in examining the spatial and temporal distributions of air pollutants over China, with a full year simulation and local observations. Although the WRF/CMAQ model has been applied in many studies over East Asia recently, this full year simulation helps to probe into the modeling discrepancy and stability. The manuscript generally introduced the performance but lacked sufficient discussion or emphasis on the findings as a research paper. More explicit discussion and demonstration of the findings are necessary to illustrate the contribution of this manuscript. Therefore, I recommend the manuscript to be accepted with minor revision if the following questions/issues are being addressed in details by the authors. Responses: We thank the reviewer for providing important comments that help improve the quality of manuscript. However, the comments are same as the quick review process before its publication on ACPD. We have responded to the comments and here we made additional changes together with other reviewers’ comments.
