Reviewer 3 Report
It is a very interesting work, well developed and presented. I have only minor comments:
- Define abbreviations when they first appear in the text, such as FDDA in line 12, CMAQ in line 16, etc.
- Add the names of chemical elements in front of the symbols when they first appear in the text.

Reviewer 4 Report
The paper Development of the Global to Mesoscale Air Quality Forecast and Analysis System (GMAF) and its Application to PM2.5 Forecast in Korea presents some interesting results for the community. The structure of the paper is logical and the methodology is clearly defined. The abstract offers concise and correct information on the remaining part of the article. The results are clear and the conclusion part is concise. In my opinion, the manuscript is suitable for publication after some minor revisions and typing corrections. Please find bellow my specific comments:
