The results of conjugated studies of contaminations of snowpack and atmosphere air by polyaromatic hydrocarbons (PAH) and soot in a number of major cities of the south of West Siberia are presented. Snow samples selected at the stationary observation stations were analyzed by the method of gas chromatography mass spectrometry (GC-MS) on the content of PAH. The results obtained were compared with the data of the Federal Service for Hydrometeorology and Environmental Monitoring of Russia (Roshydromet) on soot and benzo(a)pyrene in air. Linear correlations between concentrations of considered impurities in conjugated environments were established. The data of ground monitoring snowpack contamination by PAH were compared with the results of winter space image processing by tones of the grey colour
