On its own count the pipeline puts the observed year at +19.8 points; with the weather removed it is still +10.8 points worse, on the model's count across 31 of 31 stations. 5 of 6 pollutants show no real improvement.

From 116 to 115. The 95 per cent interval runs -9.4 to 8.8 points, on 45 matched stations, so the honest reading is level, not worse.

Today 115 across 45 stations. The year is judged on the 37 matched stations: 120 today against 99, the mean of the same date ±7 days of 2025 at those stations. The interval runs 7.1 to 37.7 points.

Very Poor, on PM10. Last year this station read 132 on the ±7-day mean around this date; the change is 188.5 points. Within 500 m of the monitor, 84% of the land is built up and 14% is under vegetation, so this reading describes a densely built neighbourhood.

On the same 225 dates the best tenth of days reads 83 against 75, and the worst tenth 303 against 301. Each is unchanged inside its margin, and the days at or below 200 went from 146 to 147.

That is 13.4 of 43.1 reporting stations, against 32 per cent over the same dates last year, a change of +0.4 points on an interval of -3.4 to +4.2, so it is unchanged inside its margin.

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.

That is 13.2 per cent of Delhi, living around the 2 monitors that read Poor or worse. Anand Vihar was worst at 320, and 1,363,291 people live within 4 km of it. On the wider count, 68 per cent live within 4 km of a monitor at Moderate or worse.
