ANNUAL AND SEASONAL RECCURANCE OF THE AIR QUALITY INDEX FOR THE TERRITORY OF SOFIA CITY
Based on 3D modelling tools, an extensive database was created and used for different studies of atmospheric composition. All the simulations were conducted with a sufficiently high resolution and with the help of the most modern modeling tools, models from the globally used US EPA Model-3 system. This gave the opportunity to conduct extensive studies on a fully competitive modern level of the climate of atmospheric composition in the country with special focus on urban area. A statistically significant ensemble of Air Quality indexes (AQI) was calculated, and their typical recurrence, space, and temporal variability for the territory of the Sofia city was constructed. The AQ impact on human health is evaluated in terms of AQI, which gives an integrated assessment of the impact of pollutants. All the AQI evaluations are based on air pollutants concentrations obtained from the numerical modelling.

This study was conducted in connection with the implementation of the National Research Program (NRP) “Environmental protection and risk reduction of adverse events and natural disasters”, approved by Council of Ministers Decision № 577 / 17.08.2018 and funded by the MES Agreement № D01-363 / 17.12.2020). Special thanks to the US EPA and US NCEP for providing free data and software and to the Dutch Organization for Applied Research (TNO) for providing the European high resolution emission inventory.
