Five “reference method” NO_x / NO₂ air quality monitoring stations supplied to Liverpool City Council. 

As part of several measures to improve air quality around Liverpool City and keep within their Clean Air Plan, five new air quality stations, complete with ‘reference method’ chemiluminescent Teledyne API T200 nitrogen dioxide analysers, which measure in real-time, were supplied and installed by Enviro Technology in city centre locations in late October 2020. As part of an ongoing maintenance package, a 3-year service and support contract with ET was also agreed.

The monitoring stations are part of the campaign ‘Let’s Clear the Air Liverpool’. ET’s Account Manager for the council, Paul Norman comments “The five, Teledyne T200 NOx analysers are housed in compact roadbox enclosures making them ideal for busy walkways, being less intrusive than traditional larger enclosures. Enviro Technology were excited to be a part of this project as Liverpool City Council are fully committed to improving the air that we all breathe and are working with a vast range of partners to make that happen.

Data is available to the public via the ‘Liverpool Air’ website  and is ratified by Air Quality Data Management. (AQMD). Designed to show real-time measurements on a colour coded map, the website also provides historic data of user selectable hourly mean values for NO₂ / NO_x at each location of the ET supplied air quality monitoring stations.

Supplied by Envitech Europe, the website also displays nearby monitoring station “Liverpool Speke” operated by the Department for Environment, Farming and Rural Affairs as part of the national Automatic Urban Rural Network (AURN).

Liverpool City Council have been committed to improving the cities air quality for some time and enlisted ET’s help previously in 2019 when they hired ET’s Smogmobile to patrol the streets monitoring NO₂, O₃, PM_2.5 & PM₁₀, CH₄, CO₂, and H₂O on Clean Air Day in order to give a second-by-second picture to identify the scale of the city’s air pollution hot spots.
