Round 1

Reviewer 1 Report

The manuscript presents a comparison of ground based lidar measurements and CALIPSO observations for BTH region. The paper is a good concept and congratulations to the authors on putting together a coherent story comparing the databases from two methods.

Key outputs:
1. vertical profiles by aerosol nature type - most useful input for further chemical transport modeling exercise
2. one year measurements and analysis

Suggestions:
1. One map showing the BTH region for which the CALIPSO data was collected - this will help visually understand the extent of satellite feeds extracted for the analysis
2. This is a good concept note and needs to be replicated. Any code used for extracting the data - this will help any other team wanting to present a similar story for other regions. This can be part of the supplementary.
3. A comparison table and notes with results from other regions, including not-China. Are we expected to see same or similar numbers, as presented in Table 2?
4. A short discussion note on the availability/coverage of CALIPSO data, how uncertainty or missing gaps are addressed when aggregating the data for the study periods
5. A discussion note on suggestions for how to integrate these results, especially the vertical profiles, into chemical transport modeling coupled with dust productions and advection in the region.

Reviewer 2 Report

  1. Could Fernald method’s assumption be very critical in certain cases of this study?
  2. What was the main factor that resulted in low correlation of EXT532 between MRL and CALIPSO as shown in Table 1.
  3. It is suggested to distinguish the line color more clearly in Figures.
  4. Did dusts and anthropogenic aerosols original from different areas have different optical properties?
  5. Since polluted dust is created to account for episodes of dust mixed with anthropogenic aerosols, what is the percentage range?
