Modeling of dry deposition of aerosol particles is presented based on a model that takes into account the influence of particle size and density, land-use categories and dynamic friction velocity in the Arctic regions of the Far North with heterogeneous land-use categories. The influence of modeling the heterogeneity land-use categories on the pollution of the earths surface due to dry deposition has been studied; the results obtained using the model used have been compared with models with averaged deposition parameters and corrections to the rate of dry deposition. Estimates of conditional contamination of the earths surface by radioactive aerosols with particles of 0.1, 1 and 10 microns in the Arctic regions of the Far North with heterogeneous land-use categories under real meteorological conditions in summer and winter were obtained.
