The manuscript presents the analysis of the impact of wind-blown dust emissions on the concentrations of PM2.5 and PM10 observed in central Europe in the period of 2007-2016. The modelling experiments are carried out with the use of chemical transport model CAMx coupled to WRF model. The structure of the manuscript, the results and the presentation of the material are very detailed and correctly worked out. The topic is relevant and suitable for publication in the ACP. I would, however, suggest a few minor changes before publication.

General comments:

In most of the cases the highest impact of wind-blown dust on PM2.5, PM10 and PM components is observed in Berlin, Munich, Prague and Warsaw. The reasons for that should be stressed in the discussion part. What are the similarities/differences for those cities?

Figs. 4, 5, 9-12, 13, 14, 15, 16, 20, 21, 22 should have the same scale of Y-axis among analyzed parameters. This will facilitate direct comparison of the analyzed values. Now, e.g. in Fig. 16 the maximum concentrations on Y-axis vary between 75 and up to 200.

Specific comments:

Line 4: replace „wind-blow dust” by „wind-blown dust”

Line 193: replace „wind-blow dust” by „wind-blown dust”

Line 292: replace „wind-blow dust” by „wind-blown dust”

Line 340: replace „wind-blow dust” by „wind-blown dust”

Line 364: replace „looked at” by „aimed at”

Line 408: replace „bair soil” by „bare soil”
