Delhi experiences its cleanest post-Diwali air since 2015. High wind speeds and above-normal temperatures kept pollution within ‘very poor’ levels, sparing the city from ‘severe’ levels
Post-Diwali Delhi Air Quality Improvement
Delhi air quality dipped to ‘very poor’ levels after Diwali, mainly due to heavy firecracker usage, stubble burning, and local emissions. However, favorable weather conditions helped in maintaining air quality within this range, marking the second cleanest post-Diwali day since 2015.
Weather’s Role in Pollution Control
High winds up to 16 km/h and above-normal temperatures played a crucial role in preventing Delhi’s air from reaching ‘severe’ levels. The AQI peaked at 362 on Friday morning but began to gradually improve by noon, reaching 354.
Contribution of Stubble Burning
Stubble burning contributed significantly to the pollution spike, accounting for 27.61% of PM2.5 levels on Diwali, up from 8.4% a day earlier. Despite favorable conditions, the rise in stubble burning has prompted warnings of worsening pollution in the coming days.
