Report · 02 September 2026

On its own count the pipeline puts the observed year at +23.8 points; with the weather removed it reads +0.5 on the model's count; the stations are too mixed to call. 4 of 6 pollutants, PM2.5, PM10, SO2, CO, show no real improvement.

The findings

What today's report says

The verdict, both rulers
On its own count the pipeline puts the observed year at +23.8 points; with the weather removed it reads +0.5 on the model's count; the stations are too mixed to call. 4 of 6 pollutants, PM2.5, PM10, SO2, CO, show no real improvement.
Against yesterday: the one-day move
From 118 to 99. The 95 per cent interval runs -24.4 to -13.9 points, on 42 matched stations.
Against last year: the observed reading
Today 99 across 44 stations. The year is judged on the 36 matched stations: 102 today against 79, the mean of the same date ±7 days of 2025 at those stations. The interval runs 16.5 to 29.4 points.
The worst station in the city today
Moderate, on PM10. Last year this station read 121 on the ±7-day mean around this date; the change is 47.9 points. Within 500 m of the monitor, 91% of the land is built up and 8% is under vegetation, so this reading describes a densely built neighbourhood.
The year, from its best days to its worst
On the same 244 dates the best tenth of days reads 84 against 73, and the worst tenth 301 against 296. Each is unchanged inside its margin, and the days at or below 200 went from 165 to 166.
How much of the city was above AQI 200
That is 12.4 of 43.1 reporting stations, against 29 per cent over the same dates last year, a change of +0.6 points on an interval of -2.9 to +4.2, so it is unchanged inside its margin.
Who the monitoring network reaches
Within 4 km live 88 per cent of Delhi's people, within 2 km 41 per cent, and within 500 m only 3.3 per cent. India's own rules ask for about 46 particulate monitors, because IS 5182 scales the count to population, and Delhi has 44. So the count test passes, while 29 of the 44 zones still stretch past 4 km, which is as far as a monitor is held to speak.
What each monitor's reading speaks for
That is 0.0 per cent of Delhi, living around the 0 monitors that read Poor or worse. Wazirpur was worst at 169, and 1,408,080 people live within 4 km of it. On the wider count, 65 per cent live within 4 km of a monitor at Moderate or worse.

A caution we publish daily

Gas data carries documented unit-inconsistency (peer-reviewed international research, 2025); we lead on the reliable PM2.5/PM10.
