Dear Jens Grundmann and co-authors,

Thank you for posting your responses to the two referees’ reports. The reviews raised some important comments and suggestions that I urge you to consider as I believe they will improve the quality of the manuscript. Based on my own reading, I find this to be an interesting paper that could fit the scope of HESS and would be of interest to the community. Yet, the manuscript is not mature enough – further information is needed to better explain the method and how it can be used in the real world. I invite you to upload a revised manuscript, incorporating the proposed changes and additions, and making any other modifications where you see fit (‘major revision’).

In addition to the comments from the reviewers, I kindly ask you to add "Author contribution" and "Data availability" sections to the manuscript, as indicated in the guidance for authors (see https://www.hydrology-and-earth-system-sciences.net/for_authors/manuscript_preparation.html).

I look forward to receiving the revised manuscript.

Sincerely,
Nadav Peleg

Dear Jens Grundmann and co-authors,

Thank you for revising your manuscript and replying to the comments made by the two referees. Reading the revised manuscript, I found it to be considerably improved in comparison to the original submission. Yet, some minor comments were suggested by the reviewers and I kindly ask you to address them. In addition to the comments made by the referees, there are some minor comments from my side that I am listing below. I look forward to receiving the revised manuscript.

Sincerely,
Nadav Peleg

Minor comments
[page line]

[2 7] Isn’t (iii) similar to (i)?

[2 10] “where rainstorms show a great variability in space and time”.Please add a reference to support this statement.

[2 16] rader.

[2 19] “A large amount of literature exists describing different approaches for space-time simulation of rainfall fields…” - I suggest also referencing here more recent stochastic rainfall generator models.

[3 8] “three-dimensional rainfall fields”. space and time?

[3 16] Replace "chapter" with "section".

[3 19] “as well as conditional rainfall simulations only”.not clear, please rephrase.

[3 30] “In order to additionally condition the rainfall field on the observed runoff it is iteratively updated”. Please rephrased this sentence.

[4 13] not Pe(x,y,t)? Please indicate what are x and t in the text.

[4 14] Ia - for each grid cell? should be - Ia(x,y)?

[4 25] Up to now… ?

[4 28-29] Repetitive.

[5 10] “After identifying the observations” - identifying how?

[8 20] The spatial extension is fixed in time?

[8 22] Figure 3 is for the total rainfall over the event or a snapshot in time? Is the synthetic storm advects with time?

[Figure 2] The North arrow in the figure can be deleted, as this is a synthetic example

[A general comment] Please use decimal point instead of a comma (i.e. replace 0,36 with 0.36)

[12 2] Why 107? And later [16 2] – why 58?

[Figure 13] I suggest moving this figure to the supplementary material.

[12 26] cell wise?

[Section 4.2] I suggest to show here examples of how the total rainfall of this event was spatially distributed (3-5 best members) in comparison to the interpolated total rainfall field from the rain gauges.

Dear Jens Grundmann and co-authors,

Thank you for revising the manuscript once again. After reading the revised manuscript, I am pleased to inform you that your manuscript has now been accepted for publication in HESS.

Thank you for your contribution and best regards,
Nadav Peleg
