Abstract: Dust dry deposition is a key component of the dust cycle in the earth system. In this review paper, we first outline the basic characteristics of dust motion in the atmospheric boundary layer and the dust collection processes at the surface. The effect of the physical features of the surface on the efficiency of dust collection is discussed. The dust dry deposition schemes are reviewed, considering dust property, surface character and wind field conditions. A summary of dry deposition schemes, measurements and model-measurement comparisons is then presented. The remaining challenges in dry deposition modeling and monitoring are discussed.

Key words: dust, dry deposition, scheme
