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)
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)
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)
