Reviewer 1 Report
Comments and Suggestions for AuthorsIt is an interesting work using Drone-Polarimetry technique to study the PLP issue of Greenhouse, and the paper is generally well written. My comments are as follows:
1) The main question bout this work is that, how do we set the thresholds for d* and a* to determine whether the insects sense a taget as the water?
2) The introduction section must be improved. The authors only mentioned two work about PLP using drone-polarimetric technique. More related works need to be introduced. The authors should also pointed out the drawbacks of the current sutdies or what issues have not been well studied in the previous work. Has the topic of PLP from greenhouse using drone-polarimetric technique been studied by researchers before?
3) This work only mention the issue that the angles (such as, the placement angle of greenhouse) can influence the sense of insects and make them misjudge the water. However, in my understanding, the flying height of insects could also infulence the behavior of insects, becaue they have olfactory sense which is helpful for them to sense water. This should be beriefly introduced and discussed. Is it possible for us to establish a new model to determine whether insects will misjudge water by considering height?
4) More references published after 2020 need to be cited.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe authors propose a Drone-based imaging polarimetry system and calculate the polarized light pollution from greenhouses and glass surfaces. Additionally, they mention a customized mounting mechanism for future studies. However, several glaring concerns need to be addressed as follows:
The significance of the polarized light pollution values from the greenhouses and the glass surfaces should be clearer. Detailed explanations are required for the data presented in Figures 1(E), 2(E), 2(J), 2(O), 3(E), 3(J), 3(O), 3(T). For instance, clarification is needed on how these measurements can be recognized as water. It is recommended to provide more detailed information.
In lines of 104 and 105, the Brewster angle of water is shown. It is not clear if the Brewster angle is adjusted when measuring polarized light pollution from the greenhouse and the glass surfaces, in which are composed of different materials.
In Figure 1, 2, and 3, the surfaces are not flat, so the incident angle might vary at different points. Additionally, the position of the sensor should consider both the sunlight and the target surface shape to ensure accurate measurements.
In the last paragraph of the discussion section, the customized mounting mechanism is mentioned. It is recommended to provide detailed information on how this mounting enhances imaging polarimetry system.
