Dear authors,
thank you for the additional work after receiving the reviews. I only have two minor requests:
1) The explanation regarding the insensitivity to BRDF (reviewer 3) is somewhat short. Can you provide a little more information and preliminary explanation? It is understood that this will be studied in more detail later, of course.
2) It makes sense that the retrieval should be rather insensitive to SSA, but could you add a somewhat physical explanation, if possible?
Please do not feel obligated to do so if you feel this is already sufficiently explain; I am only trying to make the manuscript/response to the reviewers clearer before this goes into the final stage.
Best regards,
Sebastian Schmidt

Dear authors,
thank you for adding language regarding the two points in question. This can be published - I just have one minor correction in your sentence: "However, the sensitivity to SSA is much less overwhelmed than the sensitivity to AOD and surface reflectance because the reflectance at TOA depends more on surface reflectance and AOD (than SSA in relative sense)." I think you mean "significant" instead of "overwhelmed", correct? In any case, the next step is copy-editing, so this will be picked up there.
Best regards,
Sebastian Schmidt
