Analyse de la pollution atmosphérique aux échelles locale et régionale. Modélisation spatiale et temporelle à l'aide d'une méthode de scénarii épisodiques

Abstract : To evaluate the impact of long-term exposure to an average and/or high air pollution, it is necessary to carry out long time simulations (several months, or several years). In the case of photochemical pollution, the computing time that it represents push towards intensification of runs with the parallelization of the computer codes, or towards the simulation of scenarios representative of the study period. During this thesis, we proceeded to the parallelization of TRANSCHIM code. The efficiency obtained for simulations with photo oxidant chemistry is satisfying, but the reduce time remains limited for inert simulations. Moreover, within the framework of CITY DELTA project, a method of episodical scenarios was developed to evaluate the background concentrations on Paris area. This method, based on the tri statistics of meteorological days, was validated by confrontation with measurements of monitoring sensors for the studied period (April at September 1999).
