Abstract

L5: "originating from the troposphere" => "recently transported from the troposphere"

Since "air" circulates in the entire atmosphere, there is little meaning to "origin" of air. Chemical compounds often do have clear origins but not "air" in general.

L10-11: The word "significant impact" needs adjustment. The content of the paper does not characterize the "significance" of the transport sufficiently to support the statement.

More on this point later.

L14-17, similarly, please change the wording "major importance" and "significantly contributes", because you have not shown that. Suggest to use "a contributor to the flushing..."

Intro:

L19-21, suggest to remove this first sentence. It is not a well thought of sentence and it doesn't serve as the opening sentence well. It also doesn't connect well with the sentence after.

L28, "significantly"

L60, "east Asian and Indian" => "South and Southeast Asia"

L348, "To further investigate if ..." (no comma)

L386, "... are less clear" has unclear meaning. Please be specific.

Discussion and conclusions:

Please re-consider the use of expressions such as "a major driver of the change of the Ex-UTLS chemical composition..." (L427) because the the work in the paper, although identifies Asian monsoon influences, does not quantify or characterize the overall chemical change in the Ex-UTLS by the Asian monsoon influence.

Please look at the times you used word "significantly" and be careful about it - it needs to be supported by a specific quantity.
