The study is about the particle size distribution (PSD) of dust aerosols, a hard-to-study physical parameter that is very useful in many downstream domains (such as NWP and climate projections). The authors have done an excellent job with the experiment and it is a valuable addition to the literature.

The paper is easy to read despite being quite long. I enjoyed the thorough explanations of the instrumentation and it shows the authors' attention to detail.

The only thing I found odd is that I couldn't tell how the authors combined the PSDs for multiple instruments into the final PSD presented in figure 11. A couple of lines at the start of section 3.5 would probably be sufficient.
