In the manuscript entitled “Sensitivity of biomass burning emissions estimates to land surface information”, authors explored the sensitivity of biomass burning emission estimates to land surface information under four scenarios, based on land use and aboveground biomass. This paper just provided the results of different scenarios. It seems not a sensitivity analysis. The quantification results of sensitivity indicators are not outstanding. The sensitivity of quantified single parameter could be considered. Specific comment is as following:

1ãHow to explain the meaning of equation 2?

2ãWhich variable of the formula can LCC and ACB provide data for? Please explain the relationship between LCC/ACB and emission estimation in detail.

3ãWhat is the difference between providing data by MCD12Q1 and MOD14A1?

4ãPlease supplement the discussion of the proportion of various types of biomass emissions (e.g., crop, forest, etc.) under different scenario for different LCC and AGB, and compare them with other studies.

6ãIn this paper, the different types of crops straws were not considered in the emission factors and activity data. There is comparable difference in emission factors of various crops straw, such as corn, rice, wheat, etc.

7ãIn this paper, MNM is set as the background station, whether it is similar to other pollution sources of the other two stations.

8ãLine 105-106, why the concentration of CH4 is fixed and what is the basis for setting it?

9ãLine 194-195, the data is not well expressed.

10ãFig.4: Incomplete display of broken line chart.

Short summary

This study tested combinations of two sources of AGB data and two sources of LCC data and used the same burned area satellite data to estimate BB CO emissions. Our analysis showed large discrepancies in annual mean CO emissions and explicit differences in the simulated CO concentrations among the BB emissions estimates. This study has confirmed that BB emissions estimates are sensitive to the land surface information on which they are based.
