Overview
- Delhi’s overall AQI hovered near 309–316 in the very poor band, with several stations tipping into the severe range including Alipur (421), Jahangirpuri (404) and Wazirpur (404).
- The Air Quality Early Warning System and IMD cited low wind speeds and a poor ventilation index and projected a likely severe day on November 4 before conditions ease back to very poor.
- The Supreme Court asked CAQM and CPCB to report on steps taken after submissions that only 9 of 37 monitoring stations functioned on Diwali, raising concerns about timely GRAP activation.
- Stage 2 GRAP curbs remain in force with construction restrictions, road dust control, water sprinkling and anti-smog guns, and NDMC doubled parking fees to deter private vehicle use.
- Source analysis indicated multiple contributors with transport the largest single share, substantial regional inflow and a modest stubble-burning contribution, as doctors advised vulnerable people to limit exposure or temporarily leave the city.
