Abstract

F. Cousin ', P. Tulet & R. Rosset ' I Laboratoire d 'A'rrologie / OMP, UMR 5560 CNRS Universite' de Toulouse 111, France CNRMM6t'ro-Frame TouZouse Abstract ESCOMPTE is a European pollution campaign which took place in the Marseille-FosIBerre area in summer 2001.This Mediterranean area, with its frequent pollution peaks, is characterized by a complex topography subject to sea breeze regimes together with intense localized urban, industrial and biogenic emission sources. Four IOP have been identified, the most significant being IOP 2aIb, a 6-day complex pollution episode extensively documented with surface networks, aircraft, lidar and radar measurements, constant-level balloon flights, for dynamics, radiation, gas phase and aerosols. A 2-way nested version of the MESO-NH-C meso-scale model (down to 3 km resolution) has been run for IOP 2, forced by meteorological and chemical fields issued from the global MOCAGE model (9 km local resolution near Marseille). Detailed simulations bearing upon dyn
