Suggestions for revision or reasons for rejection

P7, L139: space missing between "and" and "168" .

P13, L252: add "the" so that it reads "the model overestimates".

P13, L259-260. This sentence is somewhat weird. It should be rephrased. What do you mean with "a location of maximum"? Do you mean "the location of maximum in the CO (distribution)? Wouldn't it then be better to write "Similar to ozone the maximum in the CO distribution is not collocated with......". The second part of the sentence is also not clear and thus should be rather an own sentence. One could continue: "Further, slight differences between model simulations and MIPAS observations are found." Why are there differences between model simulation and observation? What is the reason for these differences?

P16, l326: long lived -> ling-lived

P16, L326: studeies -> studies

P16, L326: This sentence should also be rephrased. What do you mean with should behave in the model simulation similar to inert gases? I guess it should rather read "model simulation" than "model studies".

P16, L333: indicated by boxes? Where in the figure? Please clearly state that.

P17, L344-345: "of from" should be either "of" or "from".

P17, L347: add "the" so that it reads "in the Asia10 simulations...".

P17, L353: add "the" so that it reads "from the surface to ~180 hPa....

P17, L354: skip "be" after may and "to" after likely, so that it reads "may likely be".

P17, L357: It -> This

P18, L365: add "in the simulation" so that it reads "in the CTRL simulation".

P18, L376: also see -> see also

P19, L392: show -> showed

P20, L404: space between 5-6 and days is missing.

P20, L407: employ -> employed

P20, L417: evaluate -> evaluated

P21, L431ff: this text part needs to be rephrased, too. How can emission change dynamics? What do you mean with "induced by reduced of NOx and OH? Do you mean by reduced emissions or do you mean by lower concentrations of NOx and OH in the simulation?

P21, L440:show -> showed

P22, L448: One fullstop obsolete.

P22, L448-449: these leaves the question open why are there differences found. What is the reason for the differences?

Short summary

Rapid industrialization, traffic growth and urbanization resulted in a significant increase in the tropospheric trace gases over Asia. There is global concern about rising levels of these trace gases. The monsoon convection transports these gases to the upper-level-anticyclone. In this study, we show transport of these gases to the extratropics via eddy-shedding from the anticyclone. We also deliberate on changes in ozone heating rates due to the transport of Asian trace gases.
