Abstract: High ozone levels detected over large inland areas in Israel triggered an analysis of air mass back-trajectory, which pointed to the coastal Tel-Aviv metropolitan transportation system as the origin of the ozone|s precursors. In order to link the transportation emissions to ozone formation, interdisciplinary modelling systems were utilised and integrated. The transportation-to-ozone formation simulation interfaced transportation, emission factor, atmospheric and transport/diffusion models. The modelling results elucidated the spatial and temporal overlap between the ozone precursors and ozone production. The model simulations indicated an eastward transport accompanied with a 3-D expansion of the pollution cloud. The results agreed well with observed spatial and temporal ozone levels.

Keywords: advection/diffusion model; air pollution; emission factors; numerical atmospheric modelling; ozone; transportation model.
