The findings

What today's report says

Against yesterday: the one-day move

From 83 to 93. The 95 per cent interval runs 3.8 to 19.2 points, on 41 matched stations.

Against last year: the observed reading

Today 93 against 101 on the same date last year, matched stations. The interval runs -15.7 to 3.8 points, so the honest reading is level, not better.

The weather-corrected verdict

Observed, the year reads -3.3 points, level. Corrected for weather it reads +9.9. 6 of 6 pollutants show no real improvement.

The worst station in the city today

Poor, on PM10. Last year this station read 133 on the same date; the change is 90.9 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.

A caution we publish daily

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