The measurements of vertical distribution of contaminants and air temperature have revealed the presence of a permanent temperature inversion at 1-km height during the entire period of the experiment that does not allow the industrial emissions to travel aloft. The climatic data have shown that such an inversion keeps undestroyed over the whole region, even during daytime, from September until April. Even in summer, in the daytime, there exists the trapping layer at 900 to 1000-m height in this region. Therefore, increasing the height of plant stacks up to 500 m is senseless because the industrial emissions are transported below the inversion layer and their dispersal will hardly improve. In spite of high ozone concentrations, its origin is most likely stratospheric than photochemical. In summer, the vegetation around Norilsk, even at strong anthropogenic emissions, accumulates carbon. The aerosol field over Norilsk is of laminar type, with the concentration maximum in the ground or boundary layers.
