Abstract
The regional correction of the EMEP inventory data (European Monitoring and Evaluation Program) is one of the ways to improve the accuracy of model calculations of pollutant concentrations based on chemical transport models (CTM). Methods for correcting original EMEP emissions are proposed and described. On the example of CTM CHIMERE calculations for the Moscow region, the effectiveness of the application of the emission correction procedure is shown, which is confirmed by a decrease in the errors of model calculations of the PM10 concentration. The completed regional developments for the correction of emissions can be used for other regions of Russia.
