In this study are presented the results of the assessment of the impact of grid resolution on the results of computational modeling of the dispersion of air pollutants. Calculations were performed using Gaussian, non-stationary puff model CALPUFF. Four different grids resolution were analyzed. Networks were established on the basis of SRTM3 terrain and land cover classes of CLC, 2006. Analysis of results of spatial distribution of concentrations of air pollutants obtained in a regular computing grid was performed using statistical indicators recommended by the U.S. EPA. The study shows the applicability of particular computational grids in the system modeling transport …

Determination Of Optimal Spatial Databases For The Area Of Poland To The Calculation Of Air Pollutant Dispersion Using The Calmet/Calpuff Model, Robert Oleniacz, Mateusz Rzeszutek

Robert Oleniacz

The paper presents a methodology for the preparation of three-dimensional spatial data and land use data for the purpose of modeling pollutant dispersion in the ambient air using a group of geophysical preprocessors of the CALMET/CALPUFF modeling system and the GIS software. Some space information data sources available to Poland were specified and their characteristics and availability were discussed. Particular attention was turned to the SRTM3 and GTOPO30 elevation data as well as the CLC2006 and GLCC land use data, for the preparation of computational grids of different resolutions. Groups of programs which can be used in order to form …

Ocena Wpływu Nowo Budowanej Spalarni Odpadów Komunalnych W Krakowie Na Jakość Powietrza Z Wykorzystaniem Modelu Calmet/Calpuff, Mateusz Rzeszutek, Robert Oleniacz

Robert Oleniacz

The chapter presents the results of the evaluation the impact on air quality for the newly built Municipal Solid Waste Thermal Treatment Plant in Krakow (Poland) whose construction started in autumn 2013. Air pollution impact assessment was performed for air emissions adopted at the levels of emission limit values applicable for waste incineration. Modeling of air pollutant dispersion was carried out using the system of CALMET/CALPUFF models. For this purpose, the terrain elevation data from Shuttle Radar Topography Mission (SRTM3) and data of land use from Corine Land Cover 2006 (CLC 2006) were adopted with a resolution of about 100 …

Porównanie Poprzedniej I Aktualnej Metodyki Modelowania Rozprzestrzeniania Się Zanieczyszczeń W Powietrzu Opartej Na Modelu Smugi Gaussa, Robert Oleniacz, Marek Bogacki

Necessity of adaptation the Polish law in the field of the environment protection to the European Union law caused to adopt new criterions and methods of the air quality assessment. One of the methods of the air quality assessment is modeling of the substance levels in the air based on the calculation of the air pollutant dispersion in the atmosphere. Thus necessary changes also encompassed the basic methodology applied in our country for many years that had made possible calculation of the air pollution caused by existing and new emission sources. After some modifications the computation method was adopted as …

Referencyjna Metodyka Modelowania Poziomów Substancji W Powietrzu Na Tle Innych Modeli Obliczeniowych, Marek Bogacki, Robert Oleniacz

Robert Oleniacz

In the paper some differences between various computational models applied to the atmospheric dispersion modeling were presented. These models each other were compared as regards the expanse-time scale of computation, description way of the wind field and the frame of reference for the air particle moves. Particular attention was paid to the Gauss plume model that was a base for a modeling method of the pollutant levels in the air accepting in Poland as the reference methodology. A general description, applications and limitations of this methodology were presented, as well data essential to the computation, way of the data preparing …

Zmiany W Metodyce Modelowania Rozprzestrzeniania Się Zanieczyszczeń W Powietrzu Opartej Na Modelu Gaussa, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The paper presents the changes that have occurred in December 2002 in the Polish reference modeling methodology (based on the stationary Gaussian atmospheric dispersion model) used for the air quality impact assessment in Poland since the 60s of the 20th century. Discusses the changes that have occurred in the preparation of data for the simulation, the procedure used in shortened and full range of calculation, the algorithms of initial computations and the results of calculations.
