Abstract Information :

The Breathe London network, developed and operated by the Environmental Research Group at Imperial College London, represents a significant advance in operational, hybrid, urban air quality monitoring. This innovative network, in collaboration with Clarity Movement Co., has pioneered the deployment of affordable, reliable air quality sensors across London, offering an unprecedented opportunity for wider data capture and community engagement in air quality issues. With a core network of 136 sensors funded by the Greater London Authority, 60 community nodes funded by Bloomberg Philanthropies, and broad-scale buy-in from local authorities, businesses, and individuals, this initiative has equipped schools, hospitals, and underserved communities with over 420 sensors (and growing), fostering a flexible grassroots approach to environmental monitoring and advocacy. Breathe London stands out as bridging the gap between high-cost, reference-grade air quality monitors and the public's need for accessible, actionable environmental data. By integrating small sensor technology with robust data from the London Air Quality Network, the project delivers comprehensive air quality insights to individuals and community groups. This hybrid approach not only democratizes air quality monitoring but also enhances public awareness and participation in air quality improvement efforts. The network's deployment strategy and use of a unique two-stage routine calibration approach drive data reliability and support the use of the resultant network data. This methodology enables both local agencies and communities to confidently assess the air quality impacts of local initiatives, such as road closures, cycling promotions, and greening projects. Furthermore, the Breathe London Community Programme, delivering 60 funded sensors to local communities free of cost, exemplifies the project's commitment to engaging diverse community groups in environmental stewardship. Breathe London's success in mobilizing community action and providing valuable data for environmental health research illustrates the potential of sensor networks to transform urban air quality monitoring. The project's innovative model of embedded community engagement, coupled with cutting-edge technology and advanced data analytics offers a scalable blueprint for cities worldwide aiming to tackle air pollution. Through this initiative, London has not only enhanced its environmental monitoring capabilities but also empowered its citizens, making a significant contribution to the global effort to improve urban air quality and public health.
