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 …

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 …

Modelowanie Stężenia Ozonu W Niskiej Troposferze Na Przykładzie Nowego Sącza, Marek Bogacki, Marek Mazur, Robert Oleniacz

The paper presents the results of research related to the modeling of physicochemical phenomena occurring in the ground layer of the atmosphere in terms of ozone formation. For this purpose, the box model was used, in which the computational area is defined as a space designated by a steady surface and a variable height. Conducted in Nowy Sącz (Poland) experiment confirmed the possibility of using this type of model to diagnose and possibly forecasting ozone concentrations in any area of ​​calculation. The study also showed that the quality of the results depends mainly on accuracy in preparing of input data, …

The paper presents an approach for assessing the impact of road transport on the level of ozone concentrations in the ground layer of the atmosphere. The developed method consists in emission inventory on the analyzed area for road transport and calculations using the model of chemical reactions in the troposphere.

Using this method it is possible to display waveforms daily ozone concentrations in the air, and evaluate the effectiveness of the decisions related to the prevention of occurrence of photochemical smog in urban and industrial agglomerations.
