Concentrations de NO2 développement d'un SIG et influence de la météorologie à Dijon durant l'hiver 1999

Abstract : A nitrogen dioxide (NO2) measurements campaign, with passive diffusion tubes, realised by ATMOSF'Air during the winter 1999, allows to realise an atmospheric pollution study in the Dijon urban area. In order to understand the spatial NO2 distribution in the urban area, NO2 is correlated with NO emissions and topography thanks to a Geographical Information System (GIS). With a multiple linear regression, NO2 concentrations are explained principally by traffic and topography. A Principal Components Analysis shows the necessity to nuance the relation between these variables. So, the meteorological datas of Dijon-Longvic, could explain the different NO2 distribution anomalies between the six periods.
