HealthPhoto: News18Delhi's Post-Diwali Smog: AQI Discrepancies Explained
After Diwali, New Delhi experienced severe smog with the air quality index (AQI) reaching 368 at 7 am and crossing 400 at 15 CPCB monitoring stations by 10 am, peaking at 439 at Delhi Technological University. Private platforms like IQAir reported AQI above 1,000 in some areas. Differences arise because CPCB caps AQI at 500 for public health messaging, while IQAir uses US EPA methods yielding higher values. The Supreme Court allowed green crackers only on November 7-8 with a ban from November 9.
