Author comment (general and reply to referee #2)

Abstract

Please find detailed changes and remarks pertaining to the comments of referee #2 in the supplement. In addition, we would like to make the following general statement (same as for referee #1):We have read the comments of the referees with interest. It is apparent that the research is welcomed, yet its presentation needs more clarity. We have used this opportunity to make significant changes to the manuscript based on the reviewer's comments. This was done by incorporating the individual comments -as detailed in the replies to the referees -as well as by doing a 'bird's eye' revision for clarity and coherence.In the following, we address the two main points/themes raised in both reviews, and which are central to the understanding of the our work.
