Reviewer 1 Report
Recommendation: Interesting paper. My advice would be to ask for a moderate revision.
Comments:
The manuscript entitled “Measurements of aquatic particle volume scattering function up to 178.5° in the East China Sea” presents interesting work on implementing a so-called VSFlab for measurements of key characteristics of suspended particles in the East China Sea. Overall, the results are good.
I know this work has successfully designed and implemented the VSFlab. However, I am not fully understanding why the authors chose to use the VSF system. I think it will be helpful if the author can add the reasons in the introduction. In addition, Berthon et al. (2007) used an MVSM for measurements in the coastal northern Adriatic Sea. What is the difference between each version of VSF, as this VSF can also measure between 0.5° and 179°. I think it will be helpful if the authors can add the weakness and strength of VSF or compare it with other techniques as well. Alternatively, these can be the reasons why it is important to use VSFlab for the current study.
Minor comments:
Lines 483 or figure 9, “type I” and “type II” have been used but not really explained. Need clarification.

Reviewer 2 Report
Review for the paper "Measurements of aquatic particle volume scattering function up to 178.5° in the East China Sea" by Chaofan Wu, Bangyi Tao, Yilu Guo, Haiqing Huang, Zhihua Mao, Hong Song and Delu Pan submitted to "Applied Sciences".
General comment.
Remote sensing is an important tool to investigate the ocean surface. The authors conducted a study to test a laboratory-based VSF instrument to obtain volume scattering function measurements in the range from 1-178.5°. The authors provided a detailed description of this new instrument. New prism design used in the instrument allowed the authors to reduce the stray light in the backward direction more effectively than analogs. The authors applied this method to study the East China Sea and found an increase in VSF from 170° to 178.5°. The authors detected two types of VSFs with different size distribution and shape parameters. The results of this study may be useful for remote sensing of the East China Sea.
Specific remarks.
