Suggestions for revision or reasons for rejection

The topic is interesting and important for studies of land-atmosphere interactions; the maps of the surface aerodynamic roughness are very useful for modeling studies.

However the analysis and writing is far below what is needed for a scientific paper. The following suggestions must be taken into account for potential acceptance of this manuscript.

1) The writing is often not understandable and one must guess what the authors are trying to say. A English editing is a first requirement for the revision to be able further considered.

2) The abstract does not make much sense as it is now and needs to be completely rewritten.

3) The introduction part refers to everything that is happening on the Tibetan plateau. It must be shortened to introduce the purpose of the study and the organization of paper in L89-114.

4) in eq. (5), (6), the coefficients C1, and C2 are different.

5) L210, what is 'liquid surface drag' ? I guess they mean leaf surface drag here, could the senior authors read what they write carefully.

6) in discussing the possible reasons for the roughness due to snow coverage, in L273-284 in general, the authors need to add supporting information by adding albedo data.

7) The authors need to add more information on shortwave and longwave radiation (the latter for deriving surface temperature), air temperature, wind speed as a minimum, and albedo to support their discussions.

8) L306-308, and throughout the text, vague expression is used for potential reasons. This needs to be substantiated with data.

9) L399-424, this reviewer is surprised by the introductory text in this last part of conclusions. This could be utilized in the introduction more properly to support the rationale for this study.

Short summary

In this study, using MODIS satellite data and site atmospheric turbulence observation data in the Nagqu area of the northern Tibetan Plateau, with the Massman-retrieved model and a single height observation to determine aerodynamic surface roughness, temporal and spatial variation characteristics of the surface roughness were analyzed. The result is feasible, and it can be applied to improve the model parameters of the land surface model and the accuracy of model simulation in future work.
