New Delhi: Two day after Diwali, Delhi and several other cities and towns recorded ‘poor’ or ‘very poor’ air quality, especially in Haryana, Punjab, Uttar Pradesh and Rajasthan, but compared to previous years at the national level. The situation in Delhi was relatively better.
Severe air quality was observed in the national capital and its neighboring regions after Diwali, when the festival was celebrated in November during the last two years, with the region witnessing intense haze during the day. However, favorable weather conditions related to temperature and wind direction have reduced the impact of crackers and stubble burning to some extent this year.
In the last two years, the national capital and its neighbouring areas had witnessed severe air quality post-Diwali with thick smog enveloping the region for days as stubble burning peaks during the month while low temperatures and calm winds trap pollutants.
On Monday, Delhi’s air quality index (AQI) stood at 310 at 11 PM and then it increased to 326 by 6 am on Tuesday, and remained stable till 9 am and then started decreasing. It was 312 at 4.10 pm on Tuesday.
