There were 2 reviewers of this manuscript that submitted during the peer-review process.

Reviewer 1 found the MS publishable with only 2 minor revisions, whilst reviewer 2 found publish with major revisions.

I have read through the reviewer comments, and can see that the authors have replied comprehensively to each point
raised by reviewer 2, and added Figures S1 and S2, now providing comparison ground-truth aerosol observations,
and clarifying aspects of the experiment design.

I am content that the paper is publishable in its current form, and provides a good paper that explores the differences
between the high-resolution simulations with the regional-refinement configuration and the global lower-res model runs.
