The air quality in Delhi deteriorated sharply after Diwali celebrations due to fireworks, with data from many monitoring stations going missing during peak pollution hours. Only eight out of 39 stations provided uninterrupted hourly data for the period spanning Diwali night and the following morning. A total of 173 hours of AQI data were unrecorded across 31 stations, primarily during the highest pollution times. Officially, Delhi's average AQI was recorded at 351 (very poor) on October 21, but extrapolated data suggests it could have been closer to severe levels had all stations functioned properly. Despite reports of missing data, officials initially denied any issues with monitoring.
