This paper adresses a very important topic using an original methodology. The reviewers also enjoyed reading the manuscript and have provided several constructive remarks. In particular, the model description and data used need additional details and the discussion section needs to be extended, including sensitivity analyses and management scenarios. The proposed changes by the authors are in the line for taking into account rigorously these suggestions and I encourage them to perform the additional tests required. I look forward to seeing the revised version

This paper is an interesting case study of TRMM rainfall data evaluation using rainfall-runoff simulation. The main criticism of the reviewers concerns the cross-validation experiment and it appears from the authors responses that they have clearly the material to bring this topic in an interesting discussion section and I would suggest that they add this discussion and additional tests results to the revised version of the manuscript. It is good for the impact the paper will make. I look forward to seeing the final revised version.

The reviewer and I are satisfied by the way you took into account the initial review.
Please take into account the last suggestions by Reviewer 1 and submit a final version for your paper.
