This article was dedicated to modeling of snow thawing thermal balance using satellite and meteorological data. Results of previous year work showed, that approximating snow brightness temporal dynamics allows automated computation of snow melting temporal dynamic parameters, which can then be used for detection of dust-aerosol in
snow. The goal of this year research was transition from use of temporal criteria (date of active thawing, intensity of snow melting process) to thermal/energy parameters. These criteria showed to be less depended on weather differences of consecutive years, and allowed take into account relief influence. This work used remote sensing images of MODIS
radiometer, field measurements and meteorological archive data as input parameters.
Keywords: snow, snow thawing, dust-aerosol pollution, thermal balance, temporal analysis
