Maintaining, Automatic Air Quality Monitoring on SRN (NAQMN)

he monitoring network is used to inform our programme of activity to improve air quality, manage risk associated with exceeding limit values and continue to improve our understanding of the characteristics of the SRN as a source of air pollution, including the trends in NO2 and PM2.5 concentrations

The monitoring programme primarily measures nitrogen dioxide (NO₂) and particulate matter (PM) concentrations. When the National Air Quality Monitoring Network (NAQMN) was first established, there were widespread exceedances of NO₂ across t
