Simulation of air pollution in the cross-border region Bulgaria -Turkey
MetadataShow full item record
The Bulgarian Chemical Weather Forecast System, based on WRF-CMAQ models is applied with 9km resolution for air pollution simulations in the cross-border region Bulgaria-Turkey, known for its natural parks with rich biodiversity and tourism activities in summer. Model results are compared to observations from 5 surface stations focussing on PM10, O3, NO2 and SO2 in February and June 2014. The preliminary analysis based on evaluation of some main statistics (mean, correlation, temporal variation) reveals that the model system performs well for ozone in summer, while PM10 and NO2 concentrations are underestimated. The result indicate some of the air quality problems of the region - high ozone in summer, high SO2 values in parts of the Turkish territory in winter and high PM10 daily mean concentrations in winter. © Crown Copyright 2014 Dstl.
