Interactive comment on “ Development of a parameterization scheme for calculating dry deposition velocity of fine , coarse and giant particles

چکیده
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 should address this by exploring the sensitivity of their fitting to the assumed size distribution and discuss these results.

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...

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...
متن کاملSeasonal Study of Dust Deposition and Fine Particles (PM 2.5) in Iran Using MERRA-2 Data
The research results indicated that wet and dry dust deposition is a function of geographical characteristics. The seasonal wet and dry dust deposition and Fine Particles (PM 2.5) correlation in Iran with elevation, latitude and longitude results that the maximum correlation belongs to height, followed by latitude and longitude; meanwhile height and latitude are strongly and reversely correlate...
متن کاملThe Effect of Superficial Feed Velocity on the Column Flotation Recovery in Comparison with the Conventional Flotation Cells
Flotation is the most important process for concentrating mineral ores. This process may occur in any vessel such as column flotation, which has been used widely during the last decade and the conventional flotation cells. The effect of superficial feed velocity on the copper recovery was investigated using pilot-scale column flotation of "Sarcheshmeh Capper Complex". The results were compa...
