This article deals with research of temporal and spatial snow thawing dynamics around industrial
object (Omsk city) on materials of 2008 yr winter-spring seasons. 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
