Das Projekt "Szenarien fuer Strategien zur Verringerung der Luftverschmutzung: Dispersionsmodellierung in Bergregionen" wird vom Umweltbundesamt gefördert und von Ökoscience Lufthygiene AG durchgeführt. Leading Questions: How to integrate practically complex topography in dispersion modeling? How to transfer abatement strategies into emission inventories? How to consult authorities with dispersion modeling in the field of abatement srategies? How to visualize results of scenario modeling? Abstract: The dispersion model 'Airvivo', developed by the Swedish company Indic, has been applicated to two strongly air polluted alpine valleys, the Rhine valley in the region of Chur and the Mesolcina north of Bellinzona (Canton Grissons). Abatement strategies were formulated in variations in emission inventories, and the results in the air pollution field are discussed.
