Das Projekt "Scenarios of Abatement Strategies in Air Pollution: Dispersion Modeling in Mountainous Regions" wird/wurde ausgeführt durch: Ökoscience Lufthygiene AG.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.
