Dear Authors,

Thanks for your responses to the Reviewers comments.
However, please include as much as possible your responses to the reviewers to improve the manuscript.
This specifically holds for the following responses:

Ref. #1:
- response to the first question on the model assumption should be included in the revised ms.

Ref. #2:
- address the concern of the reviewer on the variable size distribution for retrievals.
- address the point of the no-volcanic eruption simulation of CARMA
- address the straylight concern
- switch extinction symbol E to symbol k . Please do not use \beta_a, because that is confusing with respect to the GD size distribution parameter \beta.

Ref. #3:
- responses to point 5 and 7 should also be used in the revised ms.
