Where this number comes from

CPCB stopped publishing hourly station data in September 2026, so the live estimate is modelled: CAMS forecast concentrations, averaged over CPCB’s own windows, scored with CPCB’s sub-index and scaled to match this city’s recent bulletins. The 4 PM figure is still CPCB’s own measurement.
