Abstract

A system has been developed for numerical prediction of concentrations of pollutants in the atmosphere and their transformation with the use of CHIMERE chemical transport model, which takes into account emissions from stationary and mobile sources and accidental emissions. Meteorological fields are forecasted using the regional high-resolution non-hydrostatic atmospheric model WRF-ARW. The system is fully automated and can be used as a tool for receiving operational information in the work of situation and decision-making centers in the cases of industrial, natural, and man-made accidents. The system was tested for a Russian region. The test results show its efficiency, a possibility of using it in operational and research work and in the development of scenarios of emergency situations anywhere in the Russian Federation, which can help to eliminate the consequences of accidents. The first results of atmospheric pollution calculation with the system are described and can be considered as test. To obtain statistically reliable results, it is necessary to have longer series of measurements of atmospheric pollution concentrations with higher resolution.
