Dr Lekan Popoola from the University of Cambridge explains how the Breathe London sensor network can help us to identify local vs non-local sources of fine particulate matter pollution (PM2.5), and how this tool can enable us to better take action to improve air quality.

The new Breathe London programme will continue to launch through 2025.
