Delhi pollution monitors went dark as AQI surged on Diwali

Delhi pollution monitors went dark as AQI surged on Diwali

What's behind this

Delhi recorded its most polluted Diwali in five years, but the true severity may have been worse than official figures because several AQI monitoring stations went offline on Sunday night during the peak firecracker period. DPCC data showed a peak AQI of 3,744 and a worst‑hour average of 1,480, suggesting the official AQI understated pollution. After the festival, the AQI fell to 371, indicating a marginal improvement. The blackout of stations has raised questions about the reliability of the reported air quality.
