This article deals with research of temporal and spatial snow thawing dynamics around industrial object (Omsk
city) on materials of 2009 yr winter-spring seasons. Automated approximation of temporal snow brightness dynamics
was made to compute necessary snow melting parameters. Influence of dust and smoke pollution on snow thawing
parameters (starting date and thawing speed) was investigated. The satellite images of MODIS radiometer and
ground measurement results were used in work. This article is a development of a previous researches and has included
additional goal of checking stability of dependence, detected in previous article. This article also includes a
more detailed view at influence of particle size to snow thawing process. An approximation of snow thawing thermal
balance for 2007-2008 was also made to distinguish different sources of energy more correctly. The OND 86
wind dispersion model was used to approximate aerosol accumulation in snow during winter season.
Keywords: snow, snow thawing, dust-aerosol pollution, thermal balance, temporal analysis
