AIR QUALITY MONITORING NETWORK AA glanceglance atat ourour airair The air quality monitoring network operating in the province of Turin is managed by Arpa Piemonte. It is composed of 23 monitoring stations (16 background stations and 7 traffic stations) and one mobile station for short measuring Annual report on data collected by campaigns. All the stations are connected to the data acquisition centre provincial air quality monitoring network by telephone lines and transmit hourly measurement result. provincial air quality monitoring network This setup allows a continuous monitoring of the main factors that may affect air quality. Location of measurement stations on the territory is a key factor to achieve a cost-effective air quality monitoring. In Sergio Dall’Olio, above sky 2014 Torino some cases the selected sites must be representative of a large portion of territory, in other cases stations must 20142014 previewpreview represent specific pollution situation like traffic hot spot or single source emissions. A strategic location of measurement points gives extremely representative information on air quality.
