Thanks Malte for this very important and technically complex piece of work which will be central to the CMIP6 effort.

I suggest to make the following corrections:
p7l12 and elsewhere: I'm fine with using "dry air mole fraction" and "mixing ratio" interchangeably, using your phrase for clarification. They reduce to the same thing in the limit of ideal gases. However, the term "concentration" is patently a different quantity. "Concentration" is not conserved under transport and is not suitable to force a climate model with. It would come in units of mol/m^3, whereas mole fractions are dimensionless. So I suggest to remove all occurrences of "concentration" from the text.

p6l6: The list of 43 gases considered in the paper include quite a few with negligible or zero GWP; they are there because they are ozone-depleting substances. Calling them all "GHGs" is therefore inaccurate. I suggest to replace "GHGs" with "GHGs/ODSs" or to find another way of consistently addressing this concern.

p9l16: An EOF is an "empirical orthogonal function" not field, as far as I know.

p9l20: Capitalize "Gram".

p20l22: Some ODSs are indeed also GHGs, but not all, see above. I suggest to insert "Some" at the start of the sentence.

p20l27: The cooling effect of ozone depletion is substantially complicated by its dynamical impact (effect on circulation) which is the real reason people have identified ozone depletion as the leading cause of recent climate change in the Southern Hemisphere.
