Round 1

Reviewer 1 Report

Originality

The work described the effects of meteorological conditions on the airborne particulate matter over the Seoul Metropolitan Region (SMR) using long-term observation data. A major finding of the study is the potentially identified associations of the daily mean normalized PM10 concertation and the surface temperature. The methodology is standard, but the statistical analysis may not be the best to use for the data. There seems to be an excessive likelihood of wrong conclusions based on the analysis as conducted.

Scientific Quality

The presentation of data is mostly sound, but is not always clear, and there is a major problem with Figure 4: the temperature is mentioned to be in K (Line 168), and it varies between -15 and 15, which is impossible. The presentation of data in Figure 4 is unreadable. The author overuses abbreviations. The use of abbreviations could be reduced to improve readability. Conclusions are based largely on uncharacterized probabilities. They do not seem to be exhaustively supported by the data.

Specific Recommendations and Requests

General comments:

The PM10 normalization approach assumes a direct correlation of PM10 pollution with the local emissions. Many factors affect PM10 pollution, and this normalization approach cannot account for them.

Line 3: “a synoptic condition” is too general considering the specificity of the study.

Line 58: it does not seem that “how climate change affects the sensitivity of PM to meteorological conditions” is explored.

Line 108: The section should be called “Results and Discussion”.

Line 256: It’s better to write “The author was supported…”

Reviewer 2 Report

Figure 1 could be improved using satellite imagine (e.g.from  Google Map)
