Reviewer 1 Report

Comments and Suggestions for Authors

1)  For better understanding the GK2A_FDA to readers, it is better to add a brief description of its basic idea.

2) How to do train? It should be clarified. 

3) Please improve the quality of some figures, for example, Fig.2 and Fig.4. In addition, some variables' meaning are not presented in Tables 1 and 3.

Reviewer 2 Report

Comments and Suggestions for Authors

I congratulation because the paper is more good. The paper has been written with order and very clear. So I only have some questions:

1- In the introduction, the fog is identified as water droplets, so inlude fog and mist. My question is if you are consider the haze, that the physical origin is different, in training o verification cases..

2- Table 2. Could you define the paremeter "# of fog"? Is it the intensity fog? How have you calculated this value?

3- Table 4 isn't clear, visually, please can you modify?

4- The figure 4 has a blank in the middle. Is it a mistake or has a explication?

5- The figure 4. In not sure if the column (c-e-h) gives some information. It is clear that the dynamic bias correction is aplied for each pixel, so the bias will be null. Maybe it's not necessary to show it, right?

6- Between the lines from 429 to 437 the letter type seems different, could you check it?

7- When the system is trained, how long need the system to get the result?
