AIR QUALITY CO LOCATION CASE STUDY AT NORWICH CITY COUNCIL
The AQY Micro Air Quality Monitor is a system designed for ambient air quality measurement. The system measures PM2.5, PM10, NO2 and Ozone, which are key pollutants that are detrimental to health and closely associated with traffic. Norwich City Council have a permanent reference air quality monitor on Castle Meadow, central Norwich to monitor ambient air quality. The location of the monitor is close to a busy bus stop, which is of interest primarily for the NO2 levels. The Aeroqual AQY Micro Air Quality Monitor was positioned on the roof of the permanent station as pictured below.
The systems were run in parallel for a period of 2 weeks and the data compared. In the charts below the data from the reference station is shown with the red line. The green line on the graph shows the data from the AQY which tracks the reference monitor well. The data showed the AQY unit returned R2 values of 0.87 for NO2.
