दिन का सार

Today, 03 November 2026, 24 hours to 4 PM: Delhi's air today is 56.8 points worse than on this date last year, which is 17.2 per cent higher, and 33.8 points worse than yesterday, on the Central Pollution Control Board's own readings. Delhi's AQI was 365.6, Very Poor, calculated with CPCB's documented formula as the mean of 57 stations' AQIs (CPCB's note "How is AQI calculated?" and its AQI Calculator; page 25 sets out the formula). Above AQI 200 today: 57 stations, Punjabi Bagh 500, Jahangirpuri 500, Rohini 500, Mundka 500, and 53 more in the station table. Poor or worse air reached 2.00 crore people within 4 km of their monitor today, 88.2 per cent of Delhi.

The year so far, 1 January to 2 November: the cleaner days of 2026 have been the dirtiest for these dates since 2019, because three days in four read above 107.4 on the particle AQI, against 93.9 on the same dates of 2025. The middle day reads 155.9 against 144.5 on the same dates last year. On an average day, 27.7 per cent of Delhi's reporting monitors, about 12 of 44, sat above 200 on the particle AQI.

रिपोर्ट क्या कहती है

Against yesterday: the one-day move

From 332 to 366. On the 57 stations that reported on both days, the 95 per cent interval runs 26.8 to 40.6 points.

Against last year: the observed reading

Today 366 across 57 stations. The year is judged on the 38 matched stations: 386 today against 329, the mean of the same date ±7 days of 2025 at those stations. The interval runs 41.1 to 74.6 points.

The worst station in the city today

Severe, set by PM10. Its PM10 averaged 516.1 µg/m³ over the 24 hours to 4 PM, 11.4 times the WHO 24-hour guideline of 45 µg/m³. Last year this station read 352 on the mean of the same date ±7 days, so the change is +147.7 points. 16.9 lakh people live within 4 km of this monitor. Within 500 m of the monitor, 82% of the land is built up and 18% is under vegetation, so this reading describes a densely built neighbourhood.

The year, from its best days to its worst

On the same 306 complete dates, 1 January to 2 November, the best tenth of days reads 76.3 against 72.4 and the worst tenth 289.5 against 315.1. The days at or below 200 went from 211 to 219.

How much of the city was above AQI 200

That is 12.0 of 44.3 reporting stations, against 29.4 per cent over the same dates last year, a change of -1.7 points on an interval of -8.7 to +4.8, so it is unchanged inside its margin.

Who the monitoring network reaches

Within 4 km live 92 per cent of Delhi's people, within 2 km 44 per cent, and within 500 m only 3.5 per cent. The map holds 55 monitors in 53 zones; 57 monitors reported today. 33 of the 53 zones stretch past our chosen 4 km proximity threshold, informed by US EPA neighbourhood-scale guidance.

What each monitor's reading speaks for

That is 88.2 per cent of Delhi, living around the 57 monitors that read Poor or worse. Punjabi Bagh was worst at 500, and 16.9 lakh people live within 4 km of it. This counts people near the monitors, not measured individual exposure.
