On its own count the pipeline puts the observed year at +15.4 points; with the weather removed it is still +1.9 points worse, on the model's count across 27 of 30 stations. 5 of 6 pollutants show no real improvement.

From 112 to 100. The 95 per cent interval runs -20 to -4.8 points, on 43 matched stations.

Today 100 across 44 stations. The year is judged on the 36 matched stations: 102 today against 88, the mean of the same date ±7 days of 2025 at those stations. The interval runs 5.4 to 23.4 points.

Moderate, on PM2.5. Last year this station read 131 on the ±7-day mean around this date; the change is 17 points. Within 500 m of the monitor, 92% of the land is built up and 7% is under vegetation, so this reading describes a densely built neighbourhood.

On the same 236 dates the best tenth of days reads 84 against 75, and the worst tenth 302 against 300. Each is unchanged inside its margin, and the days at or below 200 went from 157 to 158.

That is 12.8 of 43.1 reporting stations, against 30 per cent over the same dates last year, a change of +0.5 points on an interval of -3.0 to +4.1, 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 0.0 per cent of Delhi, living around the 0 monitors that read Poor or worse. Jahangirpuri was worst at 148, and 1,190,340 people live within 4 km of it. On the wider count, 66 per cent live within 4 km of a monitor at Moderate or worse.
