In London fixed monitors are used to continually measure outdoor air quality and the data collected is publicly available.

Councils have a small number of fixed monitors that meet Government scientific standards.

Cheaper monitors have been installed under a Breathe  London programme which includes monitors (often called nodes) installed as part of a London Mayor’s programme, a funded network of community nodes managed by Imperial College and local Council funded nodes also managed by Imperialv College.

Clean Air Barnet uses the publicly available data from these monitors to create air quality insights. As the monitors are different and are in different locations, comparison of specific data needs to be treated with caution. We therefore focus on looking at trends and averages over periods of time at locations across London to develop insights and challenge assumptions about our air quality.

Our Clean Air Barnet Insight Reports (CABINS) summarise our findings

Our Briefings provide information about the monitoring networks, sources and types of air pollution, impact on health and regulatory targets and guidelines.
