Utilisation and integration of interdisciplinary computer models into a tool for analysing ozone production from transportation sources
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.
