Dear Authors,

your manuscript entitled "Big data managing in a landslide Early Warning System: experience from a ground-based interferometric radar application" has been now reviewed by two referees.
Both reviewers highlighted some issues in the paper. My opinion is that their comments and your replies were useful for the improvement of the manuscript, definitely. Thank you very much for those detailed answers to the comments and suggestions made by referees and editor.

On the basis of this feedback, the paper can be accepted for publication after these minor revisions.
The editor will check again, for a last time, the revised version of the work.

Please note that "technical notes" are not included among the manuscript types accepted in NHESS journal (https://www.natural-hazards-and-earth-system-sciences.net/about/manuscript_types.html). Thus, please resubmit the manuscript as a research article, as done before.

Thank you again for submitting your manuscript to our NHESS special issue "Landslide early warning systems: monitoring systems, rainfall thresholds, warning models, performance evaluation and risk perception".

Sincerely,
Stefano Luigi Gariano

Dear Emanuel Intrieri and co-authors,

first of all, you can consider your paper accepted. Congratulations!
However, after reading the final version of your manuscript, I suggest only few technical corrections, mainly about acronyms and references, listed below.
After addressing these corrections, your manuscript can proceed to the final publication in NHESS journal, in the selected Special Issue.

With my best regards and congratulations.
Sincerely,
Stefano Luigi Gariano

List of technical corrections.
Line 58: please replace “ground based interferometer (GB-InSAR)” with “Ground-Based Interferometric Synthetic Aperture Radar (GB-InSAR)”, since this is the first point in the text where the acronyms GB-InSaR is mentioned.
Line 68: as a consequence, please replace “The Ground-Based Interferometric Synthetic Aperture Radar (GB-InSAR)” with “The GB-InSAR”.
Line 172: please delete “(DPCP)” from the sub-section title, since it is already defined.
Line 386 : please change “LOS (Line Of Sight)” into “Line Of Sight (LOS).
Table 1: please replace “SOD (Sensor On Demand)” with “Sensor On Demand (SOD)”. Anyway, it seems that this is the only point of the text where this acronym is used. Thus, it could be deleted.
Line 552: please add the description of the acronyms “FLaIR” and “SUSHI”; please use capital letters for the acronym “SUSHI”.

References:
Line 388-389: please replace “Colesanti & Wasowski” with “Colesanti and Wasowski”.
Line 389: please correct “Bardi et al. 2014 and 2016” into “Bardi et al. 2014, 2016”
Please check the reference list (see: https://www.natural-hazards-and-earth-system-sciences.net/for_authors/manuscript_preparation.html).
In particular, in the list, a “and” is always needed before the last (or second) author.
Moreover, at Line 637, please replace “&” with “and”.
Finally, please check the abbreviations of all journal names, according to the ISI Journal Title Abbreviations Index (see: https://www.natural-hazards-and-earth-system-sciences.net/Copernicus_Publications_Reference_Types.pdf and http://library.caltech.edu/reference/abbreviations/ )
