Reviewer 1 Report
The manuscript is well written and easy to read with only a few points where the authors can improve how the concepts are presented. The introduction is well written and describes the context and issues that inspired the study presented here, but in this section, few studies are mentioned during the literature review and there is no explanation about the details and results of previous studies. Therefore, it is not possible to reach a conclusion about innovation and the need for further studies. Also, the write-up has many language issues and needs further tidying up.

Reviewer 2 Report
The authors present methodology for extraction of information on the flooding extent of agricultural lands in China using remote sensing data and Google Earth Engine. The methodology is described thoroughly and in detail.
However, in my view, a good paper should contain a comparative analysis and some kind of justification of the introduced methods, so that my suggestions for this work are as follows:
1. The authors state that "Many flood extraction studies have been carried out by previous researchers using remote sensing technology..." It would be nice to describe how the introsuced methodology differs from those carried out before? What steps introduced by the authors made ir possible to attain better results?
2. In discussion, it would be nice to get authors' opinion on how the introduced methodology could work for the other regions regarding geographical location, type of land, etc.? In what cases we can expect good detection precision results, and where there can be problems with detecting flooded areas?
3. At least a remark on how easy it would be to implement (and what steps it will require) this methodology on governmental level for gaining practical profit such as reducing crop losses from floods?
