Delhi-NCR to be strengthened with expansion of Continuous Ambient Air Quality Monitoring Stations

• CAAQMS = Continuous Ambient Air Quality Monitoring Stations — automated stations producing real-time, hourly pollutant data feeding into the National Air Quality Index (AQI).
• Delhi-NCR network is being scaled from 84 existing stations to 157 stations in phases, under the oversight of the Commission for Air Quality Management (CAQM), Ministry of Environment, Forest and Climate Change (MoEFCC).
• Examinable as a governance-cum-environment topic: links CAQM Act 2021, NCAP, CPCB, NAAQS, and Article 21 jurisprudence on clean air.
