Title : Impact of Siberia forest fires on the atmospheric environment over the Korean Peninsula during summer 2014

This manuscript classifies two haze episodes in Korean Peninsula based on different sources, one is from the Siberia forest fire during the late July, 2014, and the other one is from urban and industrial complexes in the East China during the mid July. It also characterizes the chemical compositions of the pollutants during these two haze episodes. This manuscript is well organized, however the presentation of the results part should be improved. You should describe the figure first before you use the information of the figure to support your conclusion.


Response:
The phrase "in the middle of July 2014" has been added in lines 96-97 in the revised

MS.
Section 2. There are a lot of observations from different sites, and those observations are used in different analyses of this study.I couldn't remember where they come from when I read the later results.I suggest making a table to describe the observation data, include information like where do they come from, site numbers, collecting method, sample frequency, used in which analysis or which figure, etc.
Response: Thank you for the suggestion.We decided to add a table containing summary of measurement parameters and conditions.Following sentence has been added in line 102 in the revised MS.
"    As we already mentioned in lines 180-183, the HYSPLIT backward trajectory can be used to track general airflow pattern rather than the exact pathway of air masses.As shown in figure 3, we can clearly see similar movement of the Siberia smoke plume from MODIS RGB image in figure 3a compared to the HYSPLIT backward trajectories in figure 3b.
Line 234.ADO has dropped to less than 0.5 at late 25 July (Fig 5), and then it increases again.

Can you explain this?
Response: Following sentences have been added in lines 234-238 in the revised MS.
Because high AOD at the Yakutsk site was caused by transport of the Siberian smoke plume (Fig. 3), the sharp drop in AOD observed during 25 July can be explained by a change in wind direction at the Yakutsk site." Line 237-239.The authors demonstrate that the smoke plumes from Siberia fire would impact Korean peninsula on 27 July and 28 July in the whole manuscript.However, here the authors said the results implied one-day transport.I'm not sure which one is the real conclusion.
Response: We agreed to the reviewer' comment.Sentence in lines 244-245 in the original MS has been modified as follows.
"These results again suggest the transport of Siberian smoke plumes to the northern Korean Peninsula." Line 237-239.Moreover, the author concluded that the sharp increase in Ussuriysk site in 24 July was due to the Siberia forest fire without showing any evidence.Is it possible that this sharp increase is due to other sources?
Response: Following sentence has been added in lines 242-243 in the revised MS.
on without explanation of the whole picture.You also need a leading sentence at the beginning of section 3 or at the end of section 3.1 to inform that you will focus on the "first" and "second" episodes and you are going to show this and that, since you have a very long result section.Response: Thank you for the comment.As reviewer suggested, we have decided to show data from 4 July to 31 July not to confuse readers.The study period of figure 2 and figure 9 were modified as 4 July to 31 July.Please see the modified figure 2 and figure 9 in the revised MS.

Spatial distributions of AOD from the MODIS satellite data (Fig. 4) clearly show that the Siberian smoke plumes extended over the Ussuriysk site during 24 July 2014."Line 240-249.Poor description.First, describe left column, and then describe right column.Does the right column only represent the Total Attenuated Backscatter along the yellow lines?How did the authors define the paths of yellow lines?All these information should be included in the description.Response: A paragraph in lines 246-258 in the original MS has been revised as follows."Figure 6 shows MODIS RGB images and vertical distributions of total attenuated backscatter at a wavelength of 532 nm measured by the CALIPSO satellite during 24, 25, and 27 July 2014.The left column in Fig. 6 shows MODIS RGB images taken during the Siberian smoke episode.These images show smoke plumes originating from the Siberian forest and being transported over northeastern China.The yellow lines over the images in the left column of Fig. 6 indicate the route of the CALIPSO satellite, and correspond to the x-axis of the backscatter plots shown in the right column of Fig. 6.In the total attenuated backscatter measurement plots (Fig. 6, right), red and yellow represent atmospheric aerosol particles and white represents clouds.

Figure
Figure 6a and b clearly show that between 24 and 25 July 2014, a smoke layer existed approximately 3-5 km in height near the source region of the Siberian forest fires.As shown in Fig. 6c, the height of the smoke layer decreased to below 2 km on 27 July 2014 as it reached the Korean Peninsula."

Table 1 summaries the measurement parameters and conditions of this study."Following table has been added in table 1 in the revised MS.Measurement parameters and conditions of this study.
beginning of the results section, it is weird to only mention the point that authors want to focus
