Dear Authors,

You have received two reviews which were generally positive about the paper. Reviewer 2 questioned the novelty, but in my opinion you showed in your reply that there are enough novel aspects in this manuscript. I therefore suggest to better highlight the novelty of your research in the revised version: Clearly indicate (e.g. in the introduction) where previous research stopped and how your research adds to this.

Besides that all other remarks have to be taken into account.

With regards to the grammar, the authors have the freedom to choose their own style (but try to be consistent). Besides that it is good to know that prior to publication Copernicus Publications applies typesetting and language copy-editing.

With kind regards,

Martijn Westhoff
