The analysis of airborne PM is a very high-profile concern for municipalities in the Campania region of Italy. 

An extended study has been conducted in the urban area of the Municipality of Pomigliano d’Arco (NA- Italy) between December 2016 and February 2017, aiming to explore if and how optical remote sensing devices (LIDAR) can overcome the limits of traditional gravimetric methods of analysis. This campaign was carried out under the MONAIR project, funded by the Municipality of Pomigliano d'Arco, in cooperation with the Advanced Metrological Services Center Cesma of the University of Naples "Federico II" and ALA Advanced Lidar Applications s.r.l..

The measurements were carried out on three different sites appropriately selected, for about fifteen days. with both traditional ( Gravimetric and Electrical Low Pressure Impactor), and innovative methods ( Microjoule POrtable LIdar System realized by ALA srl within the I-AMICA co-operation).

The results coming from the different approaches are shown for comparison purposes as well as for confirming the validity of the newly introduced technique model.

The added information, obtained by LIDAR measurement of space-time distributions of PM and air dynamics, provided surprising results: they showed the presence of airborne pollutants homogeneously spread out in the city center (most likely due to vehicle exhaust gas emissions and house chimney smoke) and at the same time they allowed to downsize the impact that the nearby industrial area was supposed to have.

At the end, the study highlights how optical remote sensing helps determining pollutants source location and can pave the way for a new air quality monitoring system.
