The side menu, on the left of the screen, allows to select six different tabs:
• Environmental monitoring stations
• Pollutants and air quality
• Atmospheric data
In detail, the "Environmental monitoring stations" tab allows to view a basic map of the area under analysis on which the eight monitoring stations are identified. The sensors have been placed near the main areas that are expected to have an impact on environmental conditions, resulting from their redevelopment.
In addition to show on the map the exact point where the control units are installed, this system includes eight cards with specific information for each station: the installation site identified in the municipal area, the pollutants and the weather parameters detected.
The "Pollutants and air quality" and "Atmospheric data" tabs collect and graphically show the trend of the monitored data.
The main pollutants detected are:
• carbon monoxide (CO), an odorless and colorless gas generated during the combustion of organic materials when the amount of oxygen available is insufficient. The main source of CO is represented by vehicular traffic;
• nitrogen dioxide (NO2), a pollutant that is normally generated as a result of combustion processes. In particular, among the emission sources, vehicular traffic has been identified as the one that contributes most to the increase in nitrogen dioxide levels in the ambient air.
In the Atmospheric data tab it is possible to view data regarding:
• wind speed.
Three combo boxes allow to select the station, the pollutant or meteorological parameter and the display frequency of the aggregated data by current day, last week, month or year. It is also possible to download specific data, with respect to the selected item, thanks to the dedicated button "Download CSV" placed under each graph.
It should be noted that the data shown are detected in near real time and are not the result of subsequent processing, but are in any case subject to a validation process.
The "Alarms" tab is filled with cards when particular critical issues arise during monitoring. The alarms shown in this sheet refer in particular to the exceeding of the limit thresholds on pollutants, set starting from those reported in the national legislation. Alarms can also report information on sensor functionality.
