Dear Authors
You did a wonderful job at responding to the reviewers comments. It improved the paper content and made information in the paper better organized. I believe this paper is almost ready to be published.
I would like you to consider adding information requested by reviewers to the paper for the following comments as it would help the reader to understand information your are providing in the manuscript.
1) Comment from the Reviewer 2 was "In Figs. 6-10, 14-15, change second bracket from “[“ to “]” in Fig. captions". You answer was "The open bracket “[“ is used commonly to indicate that the last value is not included, i.e. it indicates that values included in the set go up the last value (<), but don’t equal the last value (<=). The authors wish to preserve this indication as such, as it better represents the content of the sets."

Can you add your explanation of the open brackets to the manuscript to explain to the common reader (not familiar with the common practices in the field) the meaning of it?

2) Comment from Reviewer 1 was "Figure 4, first panel: Why is the area in the tropics of missing data in the GOME panel larger than that in Figure 3?" Your response was "If all data are screened (100 % values in Fig. 3) than the DFS and other information content values are empty."
Can you please add the above information to the paper? It will make the discussion of data screening easier to understand.

Thank you for adding minor changes to the manuscript.
I made a decision to publish your paper.
Congratulations and looking forward to see similar papers that provide valuable information for researchers who use satellite retrievals for data analyses.
