DUST GENERATION AND DISPERSION (PM10 AND PM2.5) IN THE AOSTA VALLEY: ANALYSIS WITH THE FARM MODEL
Description (Dublin Core)
eng
The aim of this work is to analyze the origin and the dispersion of the particulate matter (PM10 and PM2.5) in a
mountainous region: the Aosta Valley. To meet this goal, different simulations were performed, using the flexible air quality
regional model (FARM), to study two scenarios: winter and summer situations. To evaluate the performance of the FARM model in
order to simulate the air quality situation of the selected periods, a comparison of modelled results against observed air quality data
was carried out for both primary pollutants and particulate matter next to the measurement stations . Farm performed well in
simulating especially ozone (O3) and nitrogen dioxide (NO2) concentrations, showing a good reproduction of both daily peaks and
their daytime variations. PM model results revealed the tendency to under-predict the observed values, so we tried to use a different
emission factor for the road traffic (Lohmeyer factor). The new results were good for the urban and suburban areas, but they give
over-predictions close to highways. The PM characterisation provided by the model gives good results: in some different points of
the analysis domain (mountain, plain and urban points) we found PM profiles wich reproduce expected values.
