Field-Measured Hydraulic Traits and Remotely Sensed NDVI of Four Subtropical Tree Species Showed Transient Declines during the Drought–Heatwave Event

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The authors in this paper highlighted the 2022 hot drought event which had severe negative instantaneous impacts on four Subtropical tree species forests, using remote sensing data from satellite.

The paper has significant contributions, though some of the points needs to be considered before publication:

1- The legends in Figure 1 should be revised as it is hard to see specifically (traffic network legend).

2- The overall sentence structure of manuscript needs to be revised. For example: "Specifically, we want to test the hypothesis that:".

3- In Figure 3, what is indicated by the orange straight line (is it a threshold?).

4- Is the Heading 6 (Patents) should be included in the manuscript?

5- Figure 5 should be explained in more details.

6- You should also specify the main limitations of your work.

Reviewer 2 Report

Comments and Suggestions for Authors

In their manuscript entitled "Field-measured hydraulic traits and remotely sensed NDVI of four subtropical tree species showed transient declines during the drought and heatwave event in summer 2022 of China", the authors demonstrate the indirect impact of climate change on the health and growth of various tree species, and on the drought behavior of certain specie ones, in particular four subtropical tree species. The study is based on the analysis of remote sensing images for the year 2022, through the calculation of various indices.

Overall, the manuscript is well-organized and well-written. The methodology used is coherent with the topic, though it remains rather simplistic and less than original.

The article shows a temporal analysis during the year 2022 on different indices: Temperature, RH, NDVI... The study is interesting and global and shows how some tree species, of interest in this manuscript, behave in the face of drought and climate change
