Milano-Pascal Citta Studi and Firenze-Via Bassi monitoring sites
were chosen as examples, being located respectively in a large and
very densely populated city in Northern Italy and in a medium size
and moderately populated city in Central Italy. PM10 analysis for the
two chosen sites is presented in Fig. 3, where both emission
gridded data (on the left) and its classified variability (on the right)
are shown in a neighbourhood of 25 km around the stations. The
urban background station of Milano-Pascal Citt
a Studi, is located in
a high emissions area, well inside the urbanized area. The analysis
of the gridded emission data (Fig. 3, upper left) shows that the
highest emission value is attributed to the central cell in the urbanized
area, while mediumehigh values are allocated in the
neighbourhood. The Milano-Pascal Citta Studi monitoring site is
located in an area between the cell of the highest emission values
(West side) and cells with decreasing values (East side)
