Detection of warning signal of particulate emission on the basis of fixed threshold in real-time using a lidar system

Abstract Monitoring pollutant emissions in an urban area is of primary importance order to guarantee high levels human health (by reducing the impact respiratory diseases on inhabitants) and good preservation objects (such as historical sites or buildings). The European Environment Agency (EEA) has established that maximum concentration PM2.5 for long-term exposure 10 μg/m3. By measuring light been backscattered by atmospheric particulates, lidar technique seems be a valid method provide warning signal when particulate threshold exceeded. In addition, system can also information about distance at which this research measurements traffic-originated near University Rome “Tor Vergata” analysed different times weekday obtain continuous monitoring its backscattering coefficient, values details time from provided. where traffic very heavy, so are expected.
