This article describes the extreme value analysis of tropospheric ozone level exceedances collected at seven monitoring sites in the Paris metropolitan area during May-September over the 14-year period 1988-2001. The purpose of the study is to establish whether observed trends over time in ozone exceedances of a high threshold are real or if they are the result of meteorological changes affecting the conditions under which ozone is generated. A non-homogeneous Poisson process (NHPP), with parameters depending on meteorological covariates, temporal trend and sites factor, is used to model regionally the exceedance times and sizes of daily maxima of ozone over a high threshold.We highlight the importance of non-linear methods to detect the non-linearities.
