Interactive comment on “ Development of a parameterization scheme for calculating dry deposition velocity of fine , coarse and giant particles
1. Given the size distribution assumptions made here (the specific values of the median diameter and standard deviation) how universally applicable is this parameterization? Would the fitted parameters be identical for all other log-normal size distributions which might be characterized as “PM2.5”? or are these parameters only relevant if one assumes this specific size distribution? The authors...

results from a more detailed model, but do they reproduce the REAL world?) What do these approx. mean in terms of applications in a model (regional/global) i.e. show results from an application of the approximations. Also maybe there could be some physical discussions of the functional forms (e.g. Eq. 5 are these models physically based and parsimonious?) The figures are rather poor in terms of...

RC 1. The Eq.1, which underlies the considerations, is wrong and has been disproven in several publications. Already Slinn and Slinn (1980) derived a more appropriate equation for dry deposition velocity with an artificial virtual resistance, which, unlike the Eq.1, satisfies the mass conservation requirement between the surface and reference height. However, it did not resolve the principal pr...

AC: We conducted some sensitivity tests but did not include the results in this discussion paper for the consideration of limiting the length of the paper. In the revised version, we have added a figure of the sensitivity test results and related discussions to address this comment. Briefly, the fitted parameters could change slightly and the modeled Vd using different log-normal size distribut...
