Dear Dr. Kosović and co-authors,

I am attaching a PDF version of my Community Comment (CC). It includes both general observations and specific suggestions intended to support the further development of your manuscript. I have aimed to provide constructive feedback, and I hope these comments prove helpful as you continue to refine your contribution.

Please note that the comment is somewhat extensive. This reflects the scope of the manuscript as well as my own interest in the topic. I fully recognise that many of the points raised may already be well known to you. They are offered in the spirit of open and constructive dialogue. I am also aware that submitting a lengthy, non-anonymous comment to such a distinguished group of co-authors might be bold, and perhaps not the safest career move, but I trust the scientific process (and your goodwill) will treat it kindly.

Best regards,

Etienne Cheynet

I've read and really enjoyed the manuscript. Thank you to all the authors that compiled such an, in my mind, important document. Although the manuscript really covers a lot of ground, I did miss the effect of internal boundary layers and the, still unresolved, question of how and to which extent, turbulence over forests are to be treated differently than turbulence over low vegetation. I realize these may not be considered important in the grand picture. Since it is in preprint form I noted some thoughts while reading and attach them here in case they could be useful in the revision process. Please note that this is not a full review.
