The methodology was developed within the EC4MACS (European Consortium for the Modelling of Air pollution and Climate Strategies) project with financial contributions of the LIFE financial instrument of the European Community. Monitoring data used in this project were obtained from the European air quality database (AirBase) maintained by the European(More)
Accuracy of photochemical air quality model results depends not only on the accuracy of the meteorological fields supplied to the model, but also the frequency that those fields are updated. Tests in two and three dimension, with and without chemistry, were run to identify errors that can arise due to the frequency that models are linked (or coupled) to(More)
The Po-valley located in northern Italy at the footstep of the Alps is characterized by a high density of anthropogenic emissions and by the frequent occurrence of stagnant meteorological conditions. The area has been identified as one hot spot place where pollution levels will remain problematic in spite of the application of the current European(More)
To cope with computing power limitations, air quality models that are used in integrated assessment applications are generally approximated by simpler expressions referred to as "source-receptor relationships (SRR)". In addition to speed, it is desirable for the SRR also to be spatially flexible (application over a wide range of situations) and to require a(More)
Regional and local authorities have the obligation to design air quality plans and assess their impacts when concentration levels exceed the limit values. Because these limit values cover both short- (day) and long-term (year) effects, air quality plans also follow these two formats. In this work, we propose a methodology to analyze modeled air quality(More)
