The Wang et al manuscript entitled “Quality assessment of aerosol lidars at 1064 nm in the framework of the MEMO campaign” presents the quality assessment of lidar performances at 1064 nm in order to gain the confidence for establishing lidar network in China. The experiment and results in this study could be a useful experience for regularly lidar quality assessment in a large lidar network, in particular the 1064 nm lidar have been widely used however there is very few reports regarding on their hardware assessment a lidar network. Therefore, to my opinion, it can be published in AMT after minor revision.  I have some comments as following.

The specific comments are listed below:

1. I recommend the authors to provide the differences in the calibration procedures between 532 nm and 1064 nm channels.
2. If possible, the dark noise test, telecover test, detection range test and Rayleigh fitting test of the six lidars should also be summarized and compared in the paragraph.
3. The Discussion section should be omitted and the dark measurements results should be analyzed in the self-test section.

The technical corrections:

P3L70: “at 532 nm ” to “at 355 nm and 532 nm ”

P3L74: “instruments, calibration for 1064 nm attenuated total backscatter (ATB) calibration are...” remove one “calibration ”

P3L80: reference missing?

P4L111: “Cirrus is” to “Cirrus was”

P4L113: “infrared channels” to “infrared Mie-Rayleigh channels”

P4L115: please check the grammer with the sentence

P5L130: the results of “telecover test” is missing

P5L131: please define the abbreviation of “CMA”

P6L138: since the authors uploaded the automatic “Atmospheric Lidar Evaluation program (ALiE, https://gitee.com/mualidar/cma-lidar-comparison)” somewhere, I suggest also document this work into AMT’s supplement if possible, so that it could be more benefit for the lidar community.

P6L147: what does “system efficiencies” indicate?

P7L153-154: re-write this sentence

P7L160: should symbol S be indicates not only “lidar signal” but also backscatter coefficient?

Equation 3: “δ” to “δi”

P7L173: it is unclear what does “signal issue” mean?

P8L178: “can be” to “can not be”?

P8L189: define “CST”

P10L194: unclear description

P11L203: “it is” to “they are”

P12L224: “got severe distortion” means?

P13L249: “2017” to “2021”?
