Delhi AQI Worsens to ‘Severe’ in Pockets as Citywide Average Hits 361

Stubble smoke under stagnant northwesterly winds now accounts for roughly a third of PM2.5, forecasts show.

Overview

  • Delhi’s 24-hour average AQI reached 361 on Saturday, with more than a dozen CPCB stations crossing 400 in the ‘severe’ range including Wazirpur, Bawana, Vivek Vihar and ITO.
  • The Decision Support System estimated stubble burning’s contribution near 30% on peak days this weekend, with vehicular emissions around 15%.
  • Satellite data showed 100 farm fires in Punjab, 18 in Haryana and 164 in Uttar Pradesh on Friday after a spike the previous day, reinforcing the regional smoke inflow.
  • Authorities reported ‘very poor’ to ‘severe’ readings across the NCR, with Noida, Greater Noida and Ghaziabad in the ‘very poor’ category.
  • Delhi announced staggered government and MCD work hours from Nov 15 to Feb 15 to ease peak traffic, and official forecasts indicate little near-term improvement in air quality.
