Dear authors,

your manuscript is almost ready for publication. Please read carefully what the Executive Editor Astrid Kerkweg has written: A version number of your software product must appear in the title.

It appears also that the paper contains abbreviations that are not spelled out (e.g. OE, LUT, TWP, ...). Check whether an abbreviation is actually necessary. If an item appears only once, please spell it out.

I had also problems with figure 3. Please check whether "simulated-sampled" is correct in the middle column. The main text appears in conflict with this label. Check also the label of the right column. And finally, the word "simulated" is a bit vague here. Please indicate in the caption that "simulated" means in particular "thin clouds removed".

Page 17, line 3: replace "the" by "that". (Note: line numbering is quite wrong in my printout).

Page 17, 1st line of last par.: the word "feasible" sounds a bit strange here. Please choose a better expression (e.g. reasonable, good, ...).
