The importance to integrate forecasts and observation for anthropic and natural sources impact. Study cases

Recently the World Health Organization (WHO) confirmed the harmful effects on human health of fine particulate matter (PM2.5), to which the urban population is particularly exposed. In some cases, the high presence of particulate is not due exclusively to the local anthropic impact but it can be caused by the medium and long-distance transport of pollutants. In this respect, it becomes significant to integrate in situ measurements, satellite observations and modeling tools. All this allows the determination of atmospheric circulation and therefore the circulation of pollutants. The present work deals with some cases occurred at the Environmental Climatic Observatory of the ISAC-CNR of Lamezia Terme in conjunction with some natural and non-natural events. In such a cases it was significant to identify the sources using both in situ measurements, also from remote sensing (wind-lidar, satellite, ...), as well as modeling tools.
