Hybrid Air Quality Monitoring (CAAQMS + Hyperlocal Sensors)
The future of urban air quality monitoring is now
Rapid urbanisation, industrialisation and ongoing vehicular pollution continue to severely affect air quality in cities. With cascading effects on the health and wellbeing of both the natural environment and urban populations, the concern over air pollution is growing exponentially. Emissions from industrial activities, modes of transportation, road dust and construction make up the major sources responsible for air pollution across India.
Urban air quality is particularly difficult to measure due to highly heterogeneous pollution distribution. It is therefore crucial to create a dense air quality monitoring network to better understand the spatiotemporal variations in pollutant concentration, with the ability to pinpoint hotspots.
Even as analyser and sensor technology has evolved, the CAAQMS real-time, reference quality, traceable data remains the most accurate and proven way to measure pollutants and continues to be the most reliable method of regulatory compliance to local and international standards. While CAAQMS remains the gold standard for precise, reliable and globally trusted reference standard measurements, it is often impractical to deploy them at a spatial density sufficient for measuring air quality with high spatiotemporal details.
The optimal solution therefore — and the logical future of urban air quality monitoring —lies in the implementation of a hybrid air quality monitoring network. The most effective hybrid system consists of traditional ambient air quality monitors as reference stations and localised, smaller sensor-based monitors for spatially dense data generation.
