Abstract

A simulation of dry deposition of aerosol particles based on a model that takes into account the effect of particle size and density, characteristics of underlying surface heterogeneity, and dynamic friction velocity in the Arctic regions of the Far North is presented. The effect of underlying surface heterogeneity on the results of modeling land surface contamination due to dry deposition has been studied. The results are compared with models with averaged deposition parameters and corrections to the dry deposition rate. The conditional contamination of the land surface by radioactive aerosol particles with a size of 0.1, 1, and 10 μm has been estimated in the Arctic regions of the Far North with heterogeneous underlying surfaces under real meteorological conditions in summer and winter.
