Summary:A new approach to the problem of determining the density of emission fluxes of anthropogenic impurities from distributed urban sources by the rate of growth of the integral content of impurities in the vertical column of the atmosphere in the morning hours is proposed. The method is based on the use of a singularly perturbed reaction–diffusion model describing the vertical distribution of an admixture (carbon monoxide) over a city, in combination with atmospheric CO measurements over Moscow. The vertical profile of the turbulent diffusion coefficient was calculated from the measurement data at the Ostankino television tower, and the vertical profiles of the CO concentration for different seasons were reconstructed. The average annual CO emissions from the entire territory of Moscow were calculated using model data. The reliability of the obtained emission values is confirmed by comparisons with the emission inventory data.
