ИСТИНА

Moscow metropolis is among the world's 20 largest megacities. Intensive air emissions of pollutants affect not only the state of the atmosphere above the megapolis, but also far beyond its limits. To obtain diagnostic and predictive assessments of this impact, chemical transport models are being actively developed, in particular, COSMO-ART and SILAM. As initial and boundary data for models, the results of calculations on the global ICON model are usually used, and the emission values are from the TNO or EDGAR inventory database, built on indirect data based on information on population density, fuel consumption, etc. To date, a large body of experimental data has been accumulated on the chemical composition and thermodynamic state of the atmosphere in the Moscow region, which was obtained at stations of Roshydromet, Mosecomonitoring, A.M.Obukhov RAS, Lomonosov Moscow State University, NPO Typhoon, which allows to proceed to emission estimates based on measurements and correction of TNO estimates. Within the framework of the project, the whole volume of data on the concentration of ground contaminants CO, NOx, SO2, CH4 and PM10, obtained at regularly operated Mosekomonitoring stations and at the IAPh stations from 2005 to 2014, was systematized. Observation data of impurity concentrations are supplemented by measurements of their total content in the atmospheric column NO2 and HCHO, obtained by differential spectroscopy methods (MAX DOAS, ZDOAS) at stationary stations and by passing Moscow with DOAS-equipped car. The report collected the first estimates of impurities in the Moscow region, obtained on the basis of the collected array of experimental data. The work was supported by Russian Science Foundation with grant #16-17-10275 and RFBR grant 16-05-01062 (regarding the development of the differential spectroscopy method).
