The distribution of air pollutants in urban areas is significantly influenced by the presence of various geometric structures, including buildings, bridges, and tunnels. In built-up environments, meteorological conditions may influence the accumulation or dispersion of air pollutants in specific zones. This study examines the impact of wind and atm...

Several separate data analytics models are developed to forecast 48 h ahead the hourly concentrations of nitrogen dioxide (NO\(_2\)) and tropospheric ozone (O\(_3\)). Hourly air pollution concentrations data collected at Pavlovo urban air quality monitoring station of the Executive Environment Agency (ExEA) in Sofia city for the period 01.01.2019–0...

Black carbon (BC) is one of the particulate matter (PM) components that both affects human health and contributes to climate change. In this study, we present the preliminary results of the investigation of BC concentrations in PM2.5 for two Bulgarian cites—Sofia and Burgas. The parallel PM2.5 samplings were organized in October 2020 and January 20...

Air pollution continues to be of concern for Bulgarian cities mainly due to particulate matter of aerodynamic diameter smaller than 10 μm (PM10). There is public and expert interest in im-provement of two operational air quality modelling systems - the Bulgarian Chemical Weather Forecast System (BgCWFS) and the Local Air Quality Management System (...

В тази статия са представени изследванията и получените резултати от симулираните от атмосферен дисперсионен модел разпределения на концентрациите на замърсители около жилищен блок, намиращ се в непосредствена близост до голям булевард. Симулациите са осъществени за различни метеорологични условия. Избрани са ситуации на безветрие и такива, при кои...

The output of the Lagrangian model GRAL was compared to the measured concentration data from the COST ES1006 (Evaluation, improvement and guidance for the use of local-scale emergency prediction and response tools for airborne hazards in built environments) CUTE (Complex Urban Terrain Experiment) test case 1. The observational data set was intended...

One of the main research tasks of COST Action ES1006 was testing available dispersion models in order to evaluate their applicability in real situations of accidental gas releases in urban environment. For that purpose, model inter-comparison as well as comparison against test data from wind-tunnel experiments was performed. Because of the characte...

A comparison between the output of the CFD model OpenFOAM in RANS mode, against the CODASC (COncentration DAta of Street Canyons, Laboratory of Building- and Environmental Aerodynamics at the Institute for Hydromechanics (IfH) at the University of Karlsruhe, Germany) wind tunnel database was made, for the cases, with no trees situated in the street...

The first joint study on air pollution related problems in the cross border area Bulgaria–Turkey, was carried out. Samples of wet only depositions were collect at two sites (Burgas and Kirklareli) during the period from June to November 2014. The samples were analyzed for main cations (Ca 2+ , Mg 2+ , Na + , K + , NH + 4), main anions (NO − 3 , SO...

Abstract.Some of the most important tasks within the scope of COST Action 1006 are: evaluations (by means of statistical, experimental and computational methods) for the use and improvement of local-scale emergency prediction and response tools for airborne hazards in built environments, as well as compiling a detailed inventory of different models...

A main research task of COST Action ES1006 is the evaluation of atmospheric dispersion models by their comparison against test data from qualified field and laboratory experiments and by a model inter-comparison. The model comparison and evaluation carried out for three test cases is presented, addressing the performance of the different modelling...

The WRF-AERMOD system, as the name suggests, includes WRF – a numerical weather prediction model which provides the necessary meteorological input for the integrated Gaussian dispersion model AERMOD. With some additional information provided – terrain elevations, emissions and source types, WRFAERMOD gives a 72 hour air pollution forecast for each...

Bulk cargo handling operations is one of the major factors that may cause undesirable effect to the air quality of urban and port areas in Bourgas. The air quality monitoring of the port of Bourgas is needed to deliver reliable data for air pollution assessment in the area of the port, as well as for better insight of the impact of the port activit...

This paper presents preliminary results from the first joint Bulgarian-Turkish study on air pollution in the cross-border region. The main air quality problems and available standard air pollution measurements are presented. Results from the numerical modelling with the comprehensive WRF-CMAQ air quality system are discussed with regard to the most...

Dispersion modelling of accidental release cases in urban environment is presently developed to great detail using CFD and LES models. Comprehensive data sets are developed during the recent years for evaluation of such models. Still, the first practical issue at accidental releases to run fast a model and to get fast idea of the area under danger....

Testing and evaluating available models by model inter-comparison, as well as by comparison against test data from qualified field and laboratory experiments is a main research task of COST Action ES1006. Assuming that a typical emergency response model has already been validated with regard to local-scale dispersion modelling, the existing model e...
