Dear authors,

One of the reviewers asked to see the paper again. He/she has few additional comments to your revised version. I would like to ask you to provdide a new revised version taking these comments into account. Thanks!

Hendrik

Comments from the reviewer:
Page 13, Line 19. The authors should not generalize. The measurement described in the study by Smith et al. 2016 refers to one Criegee Intermediate, (CH3)2COO and, similarly as for the reaction with water, the different Criegee intermediates are likely to decompose at very different rates. For example, CH2OO is expected to decompose at a rate of ~ 0.6 s-1 (Berndt et al. 2015).

Page 15, lines 4 to 13. Most probably the main reason is the fact that alpha-pinene has a very low yield of SCI (~0.15) and therefore, for this BVOC, the assumption is correct. One should be careful though to generalize this to all the BVOCs.

Page 15, lines 12 and 13. This sentence is misleading. This reviewer perceives it as if there is uncertainty regarding the mechanisms of production of OH from SCI in atmospheric conditions. This is not correct. It is true that it has not been yet clarified how much of the OH formed during the ozonolysis is generated from excited and how much from stabilized CI, but this will be strongly depending on the BVOC interacting with ozone and larger and more unsaturated VOCs, like ocimene, are expected to produce a larger fraction of SCI from which a large fraction of OH can be expected.

Page 15, lines 27-29. It could be worth here adding that the small yield of SCI for alpha-pinene can also be the reason for the good agreement observed despite the simplicity of the model.

Page 16, lines 12-14. The majority of the SCI formed during ozonolysis of isoprene consists in CH2OO (60%, Nguyen et al 2016) that is not forming OH during decomposition.This could explain why no interference was observed.
