Air Quality Monitoring in York
Diffusion tube monitoring in the city
In addition to real time monitoring, City of York Council also undertakes nitrogen dioxide diffusion tube monitoring at over 300 locations in the city.
Nitrogen dioxide diffusion tubes used in York are supplied and analysed by Harwell Scientifics.
The accuracy of the diffusion tubes are monitored on a month by month basis by co-locating diffusion tubes with the inlets to three of the real time analysers operated in the city. The precision of the diffusion tubes are monitored by co-locating diffusion tubes in triplicate at seven sites in the city.
Diffusion tube results
Diffusion tube results from all monitoring locations in the city will soon be available for download from this area of the website.
In the meantime, you can download historical monitoring data from our real time sites using the JorAir Reporter
