Abstract: This paper focuses on a technique for developing and implementation of a numerical modeling procedure meaning a simulation approach of air quality over the Timisoara urban area, Romania. Simulation is achieved for a reference year in the past (2010), for which all required input data (meteorology, emission & topography data) were available on a full year, in order to have a first main validation of the model. The research/study is based on (i) numerical simulation with SIRANE, meaning an urban dispersion model that integrates the street network from Timisora with the specific data for traffic and pollutant sources, and (ii) validation of the developed program, for the specific case study, upon Timisoara. The data used in model was from emissions from the traffic and the sources of pollution for Timisoara. Campaign measurements are planned in order to validate the modeling results and adapt the code, based on the on line results of the achieved on line episodes. The novelty cosnists also in the approach of the fuel consumption calculation transferred, as main source, to the tarfic pollution.
