Distribution of Dust Mass Over Particle Sizes: Impacts on Atmospheric Optics

摘要

In this paper, particle size distribution in the atmospheric dust is simulated and analyzed by a dust model. Influence of particle distribution on atmospheric features is also considered. The study was using eight particle bins ranging from 0.15 to 7.1 μm. A lognormal distribution at sources is assumed and an interactive dust-atmospheric radiation scheme is applied. The simulated dust process shows a rather high temporal and spatial variability during the analyzed dust storm event.
