Author Response

Dear Reviewer,

The authors wish to thank you for your feedback. Here are the detailed answers:

Line 4: Give the full name of CESBIO : Manuscript changed accordingly

Line 17 add more key words : We added three more keywords

Line 32 Give the full name of CNES : Manuscript changed accordingly

Line 6 Give the full name of ACIX. The Atmospheric Correction Inter-comparison Exercise (ACIX) : the full name is already in the same sentence, we move the acronym between parenthesis

Line 95 DLR，Give the full name. Deutsches Zentrum für Luft- und Raumfahrt（DRL) : Manuscript changed accordingly

Line 116 : SOS？Acronym explained

Line132 : need not to define ACIX : Manuscript changed accordingly

Line134 : define CEOS. Committee on Earth Observation Satellites : Manuscript changed accordingly

Line 139 : need not to define AERONET : Manuscript changed accordingly

Figure 1: The significant number of RMSE can be three decimal places : the figure was changed to 3 decimals

Line 213 : need not to define ROSAS : authors keep finding useful to provide the reader with fully explained acronym in the methodology section

Line 219 and 252 need not to define BRDF : authors keep finding useful to provide the reader with fully explained acronym in the methodology section

With our best regards,

Reviewer 2 Report

This is a very well written paper, and it is good to see these results published.  This will be well-received and appreciated by those who participated in ACIX, as well as the many users of atmospherically corrected data. 

Minor grammatical and or word choice corrections are provided in a separate document.

Dear Reviewer,

Thank you for your feedback on our paper. Following your comments:

1. We have modified the Figure 1 to add x-axis labels. Since both the upper and lower distribution plots share the same x-axis, we added the labels only in the bottom plots in order to avoid overloading the figure;
2. Line 193 :  there was indeed a mistake in the text, since the georeferencing issue of the tiles was related to UTM zones and not UTM time;
3. We have taken into account all your suggestions regarding mistakes in the English language;
4. All the references to Figures and Tables are now capitalized according to the journal requirements.

With our best regards,

Jerome COLIN

Reviewer 3 Report

Dear authors,

I have found the results very interesting and I am looking forward for the final publication to cite some aspects of it.

However, the extension of the ACIX-II results could have included further analysis and discussion.

I find some assumptions and explanations quite important and relevant for other sensors using the reference data you use and as conclusions to be used for further ACIX-II exercises.

I have tried to address the main ones, adding also some minor comments.

Looking forward to read your comments.
