Dear authors,

Based on the revisions and your response, I am happy to accept the manuscript subject to minor revisions.

Both referee reports were positive, however, both asked why you have chosen the index that you used and why this does not include snow. While you do not need to change the index used, please provide some additional motivation and explanation around the new index and why you have chosen to use it in the revised version of the manuscript.

I look forward to reading the revised manuscript.
