Dear Louis and Co-Authors,
Thank you for providing a detailed response addressing the reviewers points and your updated model simulations. Please provide a revised manuscript and I will send your responses and the revised manuscript back to the referees.
Kind regards,
David

Dear Louis Le Toumelin and Co-authors,

I am pleased to inform you that your manuscript will be accepted for publication subject to one small request listed below. Both reviewers and myself are satisfied with your response to the raised comments and with your final manuscript. Your paper will be an important contribution in improving our understanding of the impact of drifting snow on the atmospheric boundary layer.

Please address the minor point raised by reviewer 2:
R2Q2 - In the literature two-parameter (shape and scale, product of which is mean particle diameter) gamma probability density functions were shown to give a reasonable fit to observed distributions of snow particle diameters (Budd, 1966; Schmidt, 1984), also used by Déry and Yau (1999). Apparently MAR is using a different parameterisation. For completeness and comparison, what is the distribution parameter lambda of the chosen exponential functions after Lin et al.(1983) used in this study, i.e. lambda or 1/lambda (=mean)? Presumably these have been fitted to observations in Antarctica, which ones? Please add this information on the chosen parameter, as it would help comparing to other models.

Kind regards,
David
