314 Boutahar et al.number of runs grows according to the order of DEMM approximation taken into account.At first order, it is 1 + n, at second order 1 + 2n + n(n−1)2, at third order 1 + 3n +3n(n−1)2+ n(n−1)(n−2)6, ...Application and compraison with Monte Carlo simulation: In order to ilustratethe DEMM approach, we have applied this method to the EMEP chemistry (10 speciesand 9 reactions, ([14]). The output is computed after an integration of 150 minutes with atimestep of 900 secondes. We have supposed that the PDF for the kinetics rates k 3 , k 5 , k 7and k 8 are Gaussian distributions with a standard deviation of 20% (figure 3). We havecomputed the output PDF from the PDF of k 3 , k 5 , k 7 and k 8 with DEMM and with aclassical Monte Carlo simulation (with 10000 simulations). Results are plotted in figure4. Second-order expansion give accurate results with a small number of model runs.SO2 Concentration profileO3 Concentration profile10300POLAIR0DFEOMPOLAIR0DFEOMConcentration (mol/cm3)98Concentration (mol/cm3)20010070 500 1000 1500Time(min)NO Concentration profile00 500 1000 1500Time(min)NO2 Concentration profile4080POLAIR0DFEOMPOLAIR0DFEOM3060Concentration(mol/cm3)20Concentration (mol/cm3)40102000 500 1000 1500Time(min)00 500 1000 1500Time(min)Figure 2.

Conclusion and future workWe have reviewed in this paper some strategies that may be used in order to computereduced models and PDF for atmospheric chemical mechanisms. In the future we willuse the HDMR Method in a three-dimensional eulerian models (namely POLAIR, [13])with a focus on multiphase chemistry. POD approaches will be tested as well as look-upTAMTAM –Tunis– 2005
