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 …

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 …
