Dear authors,

Thank you for providing a point-by-point answer to all the issues raised by both reviewers. I believe you've done a nice job covering the (relatively minor issues). Nevertheless both reviewers referred to the advantage of providing a bit more of background literature on the drought topic as well as some additional validation metric supporting the better performance of the revised CDI.

I invite you now to submit a revised version of the manuscript that include all the changes and those clarifications/improvements mention in your answering letters.

Best regards

Ricardo Trigo
