AIR QUALITY CO LOCATION CASE STUDY AT ELEPHANT & CASTLE
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. The London Borough of Southwark have a permanent reference air quality monitor Elephant and Castle to monitor ambient air quality. The location of the monitor is close to a busy intersection in an urban environment. Three Aeroqual AQY Micro Air Quality Monitors were positioned on the roof of the permanent station as pictured below:
The systems were run in parallel for a period of one week 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 graphs show the data from the AQY which tracks the reference monitor well. The data showed the AQY unit returned excellent R2 values from 0.8 to 0.92 for NO2.
