ED: Reconsider after major revisions (further review by editor and referees) (01 Aug 2020) by Harrie-Jan Hendricks Franssen

Dear Dr Beck,

Your manuscript “Evaluation of 18 satellite- and model-based soil moisture products using in situ measurements from 826 sensors” has been subjected now to review by four reviewers, three of them invited by the journal. There was in addition one spontaneous review. All the reviewers agree that your paper is of interest to HESS and most of the reviewers think that the contribution is of high scientific interest. All invited reviewers recommend major revision. Given the large amount of comments and the need for additional model evaluations you should check whether revision is feasible. I recommend major revision, and as a summary, the main points to be handled in the revision are: (i) a better motivation for the selection of the different datasets; (ii) an improved analysis taking into account the vertical representability of the in situ and remotely sensed measurement data (e.g., difference between active and passive products); (iii) the temporal resolution of the analysis; (iv) verification with in situ data, for the case that multiple in situ sensors are located within a remotely sensed grid cell; (v) other clarifications of the methodology; (vi) the calibration of the HBV-model using a different precipitation dataset as input; (vii) handling in the discussion section the point that the methodology would be biased towards the model products.

In your answer to the main points and also the many detailed comments, please indicate how comments have been handled exactly, indicating also whether text has been deleted and what the position of newly included text blocks is. Preferably, cite the newly added text in the manuscript. I am looking forward to the new version of the paper.

Best regards,

Harrie-Jan Hendricks Franssen – editor

Short summary

We evaluated the largest and most diverse set of surface soil moisture products ever evaluated in a single study. We found pronounced differences in performance among individual products and product groups. Our results provide guidance to choose the most suitable product for a particular application.
