The article presents results demonstrating the possibility to use satellite data to assess contamination of a territory. A method to identify areas of environmental pollution around industrial facilities in the tundra zone is developed. It is based on comparison of the results of chemical analysis of snow samples and spectral characteristics of the surface, which is an interpolation based on linear regression. The optimal conditions for building a raster content evaluation of individual components of pollution affecting the spectral characteristics of snow cover were selected. The accuracy and efficacy of this method in the analysis of the impact of industrial enterprises in the tundra zone were evaluated. It is shown that the accuracy of the estimated raster content of substances in the snow is comparable to the error characteristics of the methods of quantitative chemical analysis. The intake of substances on the studied territory of Vorkuta agglomeration with winter precipitation and distribution of pollution around industrial facilities were estimated. The component content in the snow of sanitary-protection zones and background areas was calculated. The calculations showed that the average content of macrocomponents for the winter period in sanitary-protection zones is 2.9 g/m2, which is approximately 6 times higher than in the background areas.
