The Central Environmental Authority (CEA) has a new site for real-time air quality updates across Sri Lanka. The National Air Quality Network dashboard includes a live AQI (Air Quality Index) for select areas, a historical analysis and comparative analysis tool, along with general alerts and notifications.
Available in all three languages, the National Air Quality Network monitors six pollutants: PM2.5, PM10, Ozone (O₃), Carbon Monoxide (CO), Nitrogen Dioxide (NO₂), and Sulfur Dioxide (SO₂). Additionally, it tracks CO₂, Volatile Organic Compounds (VOCs), and other weather factors. The data itself gets updated regularly with regulatory particulate monitors every hour, gas analyzers every 1–5 minutes, and low-cost micro-sensors every 1–15 minutes “depending on configuration” according to the CEA.
The dashboard is maintained by CEA with contributions from the National Building Research Organization (NBRO) and funding from the Vehicular Emission Testing Trust Fund (VETP). The CEA is reportedly looking to add more institutions in the future.
