Stubble burning is decreasing, but air quality remains ‘very poor’; winds are expected to provide aid. On Sunday morning, the air quality in Delhi was rated as ‘very poor’, according to SAFAR, with an overall AQI of 347. According to the Ministry of Earth Science’s air quality monitor, System of Air Quality and Weather Forecasting And Research (SAFAR), air pollution levels in Delhi managed to remain in the ‘very poor’ category on Sunday morning. Despite the fact that the impact of stubble burning on the city’s air quality has decreased dramatically due to a drop in field fires in neighboring states, the impact of stubble burning on the city’s air quality has increased.

According to SAFAR, the city’s overall Air Quality Index (AQI) was 347 at 6 am today, with particulate matter (PM) concentrations with diameters of 10 and 2.5 microns at 301 (‘bad’ category) and 181 (‘very poor’ category) correspondingly.

While north-westerly winds are ideal for transporting stubble-burning-related pollution to Delhi, the effect on Delhi’s PM2.5 (particulate pollutants) has decreased as wind speed has decreased, according to a SAFAR official release. At PM 2.5, agricultural residue burning accounted for 30% of all fires on Tuesday. Due to moderate surface winds, Delhi’s air quality improved somewhat to the ‘very poor’ category on Monday, after three days in the ‘severe’ category following Diwali.

- between 51 and 100 are regarded as ‘satisfactory,’
