Reviewer 2 Report
This study is a first step to develop a GPP monitoring system with high resolution satellites. The results were supported by 64 eddy covariance sites representing different Plant Functional Types. Thus, I think the remote sensing data was strongly validated. I think that the article is well written and results and discussion are clear to the audience. I have only one suggestion to the authors, maybe it would be a good idea if you could add a conclusion section to the article to make clearer the most important ideas.
Minor comments:
Line 68: The P model is a LUE model instead of is an LUE model.
Line 310-311: See the Error message of reference not found
Author Response
We thank the reviewer for that encouragement. In the revised manuscript, a short Conclusion section is now provided at the end of the Discussion.
Line 68: thank you, now corrected.
Line 310-311: that reference is to Figure 2 in the main text. The internal referencing was lost upon conversion to pdf format. In this version I have converted the link to plain text.
Reviewer 3 Report
This manuscript is beyond my professional knowledge. I am not qualified to evaluate its academic contribution. From my background, I can only evaluate the contents of lines 208 to 217.
I agree with the statistical relationship between LST and temperature in this part, and this relationship will change with the surface vegetation coverage. In general, the higher the vegetation coverage, the better the fitting degree of the two.
From the perspective of a non-professional reader, this article is reasonable in structure, clear in logic and clear in conclusion. Besides, I can't make other comments. A few comments are for reference only.
