  • The national capital’s air quality turned “poor” on Sunday as wind direction changed to northwesterly.
  • After fluctuating between “poor” and “very poor” for over a week, the city’s air quality had improved to “moderate” category on Saturday, mainly due to a squall in Delhi that dispersed pollutants and rainfall in neighbouring areas that subdued the effect of stubble burning.
  • The System of Air Quality and Weather Forecasting and Research (SAFAR) said the share of smoke from stubble burning in Delhi’s PM2.5 concentration was 13 per cent on Sunday, the highest in over a week.
