The paper presents a study on photosynthetic and VOC field measurements made by a novel combination of well-established methods (PPS, CIMS, GCMS). The scientific methodology used is good, the writing is now clear and exhaustive and the graphics are clear and all good standard. The results presented are very useful for the scientific community, providing a thorough characterisation of this measurement system of VOCs in connection to photosynthetic activity: such system has a potential to aid the wider detection of plant VOC dynamics, also in relation to the changing atmosphere dynamics.
I would personally like to thank the reviewers for the careful work they provided, making it easy for me to proceed with the final editing steps.
The authors have provided the requested information by the reviewers both in terms of added references and added details concerning their study. New results were added to the original manuscript, adding value and clarity on the required issues: a new graph has been added illustrating dynamics of more monoterpene than the original two. Clarifications on the methodology have been expanded, and answer the questions brought up by the reviewers. Further material has been added to the supplement, to report data that could be useful for other purposes as well.
