Best practices from Breathe London — Lessons learned from integrating air quality sensors with the most advanced regulatory monitoring network in Europe

Breathe London, the community sensing network

Learn what makes the largest air quality sensor network in Europe work!

Over 350 air quality sensors are installed in boroughs across London through the Breathe London program. Every Node-S air sensor is co-located at reference sites and checked by researchers at Imperial College London before deployment. Once deployed, data are continually cross-checked against reference sites in real-time.

In this panel discussion, the operators of this network — Imperial College London, the Greater London Authority, and Clarity — share valuable information and real-world learnings about the use of air sensors at the city scale.

Topics include:

  • Distribution - who should own the sensors, and how should they be distributed to ensure equitable air monitoring coverage?
  • Siting and installation - how to select and prioritize monitoring sites? What indemnity provisions should be made, who is responsible for maintenance, and who is liable for making sure devices are properly installed?
  • QA/QC and calibration - how to ensure data accuracy?
  • Community engagement - how to use a sensor network to build relationships between community groups and local government?
  • Research applications - how has data from the network been used for case studies and research, and what other potential applications exist?

Guide includes best practices from: 

  • London

    London Colocation
    The Greater London Authority (GLA) funded more than 100 sensors to complement the existing, dense network of reference monitors in London. This network has revolutionized Londoners’ access to reliable air quality data and provides GLA higher-resolution data.

  • Paris

    150 low-cost sensors were installed at schools across Paris in September 2019 to provide new information and insights on air quality. The data is collected, analyzed, and integrated into the existing air quality monitoring and mapping system operated by Airparif.

  • Bangalore

    A building in the city of Bengaluru, which is using Clarity Nodes to measure its levels of fine particulate matter
    The Global Climate Health Alliance (GCHA), the Health and Environment Alliance (HEAL), and the Healthy Air Coalition installed 30 indicative air quality monitors across the city in 2019. The network was deployed at strategic locations to gain actionable, local data.
