Interesting process and product, thanks for considering ESSD.

Small changes and improvements suggested:

Page 2 line 30 “merging them with the those obtained at 30 arc-sec”: delete ‘the’

Page 2 line 40: something wrong here? The TI equation looks correct but why the (m) e.g. a(m), in the text? (m) indicates the units, but in which case it should be m**2?

Page 10 line 1: you use this identical sentence on page 8, line 15. Specify it there, then here write something like ‘as explained above’? We should not get identical phrase in two locations.

Page 10, wetness indices defintions: as both reviewers commented, these paragraphs and equations really belong in section 2 about data processing. Here in section 3 you want to focus on the composite maps. No re-writing necessary but to move some paragraphs would make a substantial improvement?

Page 13 line 8: “our two CW maps”, but you have 7 CW maps, which two? The two preferred CW maps described on page 17? Later in this paragraph (line 35) you mention “four of our CW maps”. A reader does not know which two or which four maps you refer to and looking at figure legends does not always help.

Page 15 line 5: “Jaccard index rises from 46 to 53”. But, JI varies between 0 and 1 (page 12).
