Reviewer 1 Report
Comments and Suggestions for AuthorsThe atmospheric boundary layer is the most important layer of human activities. Remote sensing of vertical structure of boundary layer is very necessary for local weather and environment research. This paper has a clear significance for the study of the effect of anthropogenic thermal emission on the structures of boundary layer over a large factory. The following modifications are recommended before the article is accepted.
1. The information of the observation station is somewhat confusing in 2.1 section. Suggest to give the relevant information of the boundary layer remote sensing clearly, such as the surface types, anthropogenic heat source in the local region.
2. The instruments are the current international traditional advanced equipment. To give a brief description and add data quality control.
3. The differences between thermal, dynamic, and material structures are compared. Is there a connection between them, or mutual influence? Need to be discussed in depth.
4. Figure 4 is not intuitive, and it is recommended to modify it.
5. Atmospheric diffusion capacity of BLH seem be unclear in figure 6, because the corresponding emissions are highly uncertain. Then make clear its scientific significance.
6. English and grammar are checked and revised throughout.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe paper by Xinbing Ren et al. investigates planetary boundary layer structures over over a single strong anthropogenic source. It focuses mainly on ground active sensors that provide information on the vertical dimension. The paper is well within the scope of the journal. The methodology and analysis are thorough and well documented. I suggest minor revisions before publication.
In the following, specific and technical comments are given for consideration.
specific comments:
Introduction： the authors should give the definitions of thermal, dynamic and material boundary layer，and the aims to study them.
Section 2.1. please give the pollution feature over observation site after describe the main production facilities.
Line 142-143: it is a inappropriate description and nothing to do with the topic, so suggest to remove this sentence.
Line 146: please explain “radial wind speed range” and what to obtain the horizontal wind speed?
Line 147-150: re-write this unclear sentence.
Line 157: “The CL51 cloud altimeter samples the return signal every 67 ns between 0 and 100 μs, providing atmospheric backwards” remove the technique details and to add more data sampling details.
Line 158: “from the ground to an altitude of 15 km with a spatial resolution of 10 m. The CL51 ”no blind zone?
Line161: “pulses of high power ” remove such vague technique details or add the parameter table for them.
Line 165-167: since how to obtain planetary boundary layer is very important in this study, so the authors should give a clear methodology how the planetary boundary layer obtained using lidar and give a reference. A reference as example includes the planetary boundary layer calculate method as following:
Wang, L.; Stanič, S.; Bergant, K.; Eichinger, W.; Močnik, G.; Drinovec, L.; Vaupotič, J.; Miler, M.; Gosar, M.; Gregorič, A. Retrieval of Vertical Mass Concentration Distributions—Vipava Valley Case Study. Remote Sens. 2019, 11, 106. https://doi.org/10.3390/rs11020106
2.3.1: I can not understand the motivation of this part. Why the authors adopt potential temperature to classify the atmospheric conditions? And what is difference with Gradient Richard number?
Line 208: “n denotes the number of vertical levels within BLH” it is unclear.
In general, the authors must give a descriptions how the different BLH was obtained.
Figure 1: mark the north direction in the wind rose.
Figure 2: relative humidity is 100% during 06-07 to 06-18. Is it raining? If yes, how the BLH obtained from lidar?
Figure 3: how to define the direction? what is the vertical wind speed do for here?
Figure 4: zoom in the rose plots.
Technical Comments:
The format need to be organized,e.g. page 5 leaves blank space.
Line 140: “backward scattered” changes to “backscattered” .
Line 145: “time resolution” -> “temporal resolution” and to add spatial resolution.
Line 152: “ remote sensing device “ -> “active remote sensing device”
Line 183: order the equations and give the sequence numbers.
Check the typos. Such as humidty -> humidity
