About Our Air Quality Monitoring Network
Breathe Metro Manila consists of a hybrid network of reference-grade air quality analyzers owned by DENR-EMB alongside air quality sensors. Sensors are not as accurate as reference monitors but can be used to identify and characterize air pollution at high spatial and temporal resolution.
Breathe Metro Manila has teamed up with Clarity Movement Co., a distinguished sensor company headquartered in California that engineered the Node-S, a lightweight and compact sensor designed to measure PM₂.₅ particulate matter and nitrogen dioxide (NO₂). The Node-S pictured to the right is from Quezon City’s network of 40 Clarity Nodes, which was deployed in 2022 and forms part of the core Breathe Metrol Manila air quality monitoring network.
Solar-Powered Node-S
The Node-S can operate using solar power, making it suitable for deployment across large urban areas like Metro Manila. This advanced device has been successfully deployed in more than 70 countries globally, and has undergone rigorous evaluations by the South Coast Air Quality Management District in California and Airparif in Paris, ensuring its reliability and accuracy in air quality measurement.
Ensuring Data Accuracy and Reliability
At Breathe Metro Manila, we prioritize the accuracy and reliability of our air quality data — which is why all Breathe Metro Manila Nodes are co-located with DENR-EMB NCR reference monitors before being deployed . By co-locating our sensors alongside reference monitors (pictured), we can rigorously assess their performance.
This process enables us to derive a device-specific correction factor that is carefully adjusted to reflect local conditions at each co-location site. Once deployed, Clarity’s team of air quality experts evaluates the performance of the sensors against specific statistical targets, ensuring their long-term accuracy and effectiveness in monitoring air quality.
Who runs the Breathe Metro Manila network?
The Breathe Metro Manila network is managed by the Manila Observatory, supported by the Department of Environment and Natural Resources - Environmental Management Bureau National Capital Region (DENR-EMB NCR), other local environmental agencies, and Clarity.
The Manila Observatory, established in 1865, has a distinguished history of contributing to the Philippines' understanding of environmental and atmospheric sciences. Initially serving as the country's official meteorological and seismological agency, it transitioned to a non-profit research institution post-World War II. Today, the Observatory leverages its extensive expertise in atmospheric and earth sciences, remote sensing technologies, and data sciences to address climate change and enhance disaster risk resilience.
Through its commitment to applying science in practical ways, the Observatory develops and supports policies and practices that directly meet societal needs, making it exceptionally qualified to lead the Breathe Metro Manila initiative. This deep integration of scientific research and community-oriented action equips the Manila Observatory to effectively manage the network and drive significant environmental improvements in Manila.
How is the network funded?
The initial funding for the deployment of Breathe Metro Manila's sensor network was generously provided by the Department of Environment and Natural Resources - Environmental Management Bureau National Capital Region (DENR-EMB NCR) and the Quezon City government. This collaboration was facilitated by C40 Cities, a network dedicated to addressing climate change. The funding supported the initial batch of sensors, enabling us to establish a robust foundation for air quality monitoring throughout the city.
In addition to government support, we seek partnerships and sponsorships to expand and maintain our network. These collaborations focus on placing sensors in critical locations such as schools and hospitals and enhancing community engagement through targeted monitoring and educational initiatives.
Through advanced air quality monitoring technologies and community engagement, we strive to create impactful changes in air quality policies and public health awareness. Our real-time air quality data helps identify pollution hotspots and tracks air quality trends. This data supports our mission to advocate for cleaner air through science-based policies and practices.
