The numerical analysis of the data of the aircraft sounding plume of impurity carry-over in the summer atmosphere of the Norilsk industrial region has been carried out. A two-parameter model was constructed for numerical retrieval of impurity concentrations in directions transverse to the plume and, based on it, estimates of the lower limits of sulfur dioxide emission corresponding to different emission time. Considerable variability of emission estimates was established due to the nonstationarity of sulfur dioxide emissions into the atmosphere. The average emission of SO2 into the atmosphere was estimated as 1.86 million tons/year, which is close to the official statistics.
