Delhi AQI Discrepancy: Official Readings Show 370 While Private Platforms Report 1,000
· India · Indian Express, Business Standard
Delhi's official Air Quality Index (AQI) registered 370 on November 9, 2026, placing the city in the 'very poor' category after Diwali firecracker use. Several monitoring stations recorded readings above 400, crossing into 'severe' territory. Private platforms reported figures as high as 1,000, but the article states these cannot be directly compared due to differing AQI scales and measurement methods. The Indian AQI system, launched in 2014 under Swachh Bharat, converts eight pollutant measurements into a single index where the highest sub-index determines the overall category.
Why it matters
Delhi residents face health risks from 'very poor' air quality while conflicting data sources create confusion about actual pollution levels.
