Dear Dr Bossolasco and co-authors,

one of the reviewers has had a look into the revised version of your manuscript. They found that over all, you have carefully considered their comments in the revised version, while some minor issues are still open. I am asking you to consider these minor reviewer comments in a further revision of your paper.

Thank you very much!
Best regards,
Gabriele Stiller

Dear Dr Bossolasco and co-authors,

thank you very much for the revision of your manuscript. In my opinion, the issues raised by the reviewer have been tackled appropriately. However, I have one remaining issue related to Fig. S1: In this figure, you interpret the MLS data in a step-wise manner, i.e. each vertical data point represents the constant, i.e. average, value of a layer (between this and the adjacent pressure level, I assume; however, how is the pressure interpreted then? Top of the layer, bottom of the layer, center of the layer?). To my understanding, however, the MLS data should be interpreted as vmr values at a certain pressure level, with linear or logarithmic interpolation in between. If linear or logarithmic interpolation depends on the retrieval of vmr of log(vmr), respectively. Please could you check if your interpretation of MLS vmr data is correct, and revise this figure if needed?

Kind regards,
Gabriele Stiller
