Versione italiano English version

PMetro is a novel approach to characterize urban particulate matter, which exploits a mobile platform integrated on a Minimetro cabin and combines real time measurements with the data from the local Environmental Protection Agency (ARPA).

The graphs illustrates the daily evolution of number concentration (particle/L) of fine particles (diameter Dp< 1.1 µm) and coarse particles (diameter Dp>1.1 µm), as recorded by the mobile cabin along the Minimetro path (approx 3 km long). The color scale indicates the concentration levels between a minimum (blue, estimated on the average values recorded at the background regional site) and a maximum (red, estimated on the basis of the law limits). The red and blue concentrations are different for the fine and coarse fractions.
