Dear Martin et al,

Thank you for your revised manuscript that fully answers the reviewer's remarks. I think the manuscript is ready for publication but for the following minor comments from my side that I ask you to consider in your final version (the lines and pages refer to version5 of your manuscript):
-p.2, l.31: correct "oragnisational"
-p.2, l.48: remove the comma in "The data requirements, include"
-p.3, l.60: put the exact reference. i.e. the year, in "described in Balaji et al.,"
-p.5, l.98: I think you should remove "but" in "and the ocean — but here we have 50"
-p.5, l.104: Add "as" in "which is fortunate, it would be"
-p.6, l.131: Consider changing "impractical" for "unfeasible"
-p.6, l.137: Consider changing the sentence for "Delivering on the above high level requirements led to four ..."
-p.10, l.180: you write "parameters and requirements" but Table 3 contains "attributes", can this be made coherent?
p.11, l.202: add "and " in "in the DREQ, the total number"
-p.17, l.323: maybe rephrase "there is a great deal more organised structure ..."
-p.19, l.386: add "in" in "than previous CMIP exercises"
-p.20, l.401: change "it's" for "its"
-p.20, l.419: maybe change "complicated" for "complicate" or "complex"
-p.21, l.434: Remove "The" in "The following this and subsequent ..."
-p.21, l.443: Like for the other bullet point, make a full sentence out of this bullet
-p.22 l.463: consider changing "for it to meet" for "for them to meet"

Thank you and best regards,
Sophie
