Impact des conditions météorologiques locales sur la variabilité spatiale de l'ozone à échelle fine à Nice

Abstract : The city of Nice is strongly affected each summer by ozone pollution. Thanks to many measurement campaigns from April to September 2007 in Nice, the ozone spatial variability was apprehended at fine spatial scale. The secondary pollutant spatial average offers a coastal and suburban areas characterized by higher concentrations than the rest of the surveyed areas. Apart from the impact of primary pollutants fugitive emissions by the motor traffic in urban and suburban, local weather conditions also govern the spatial ozone distribution. To what extent the spatial variability of certain meteorological variables influence the ozone spatial average ? The use of deterministic model RAMS (Regional Atmospheric Modelling System) provide numerical simulations to fine scale to answer this question.
