The main innovation of this project is related to the investigation of the origin of aerosols episodes occurred over Portugal and Germany, using the EURAD-IM air quality modelling system improved with observational data (data fusion/assimilation techniques). This project will contribute both to explain aerosols episodes and to improve the 4D-var (data assimilation) and RAT (data fusion) techniques, developed by the German and Portuguese partners, respectively. The outcomes of this exploration will support more efficient and effective regional/local air quality plans in the scope of the European air quality Directive, while promoting the development of more robust techniques to combine observational data with modelling tools.
