Delhi's average PM2.5 today is 32.8 µg/m³ and PM10 is 83.8 µg/m³. 39 of 44 stations breached the WHO limit for PM2.5; 39 of 42 breached it for PM10. Gas monitoring was down on this date, so this edition reports the two particulate pollutants directly, in micrograms per cubic metre, and publishes no composite index figure.

Even after removing the weather's help, Delhi's fine-particle level (PM2.5) is 36 micrograms per cubic metre (µg/m³), which is 2.4× the WHO safe limit of 15. The worst weather-corrected hotspot is Wazirpur at 50 µg/m³, which is 3.3× the WHO limit.

After weather correction, 34 of 34 comparable stations are worse than last year. This is a city-wide rise, not a few bad spots.

On days it has never seen, the weather-correction model explains about 38% of the variation, so we treat its outputs as estimates, not exact points. The weather-corrected year-on-year change for fine particles is measured to within roughly ±1 percentage points of sampling error, before model uncertainty. Gas monitoring was down on this date: NO2 reported from 10 stations, SO2 reported from 9 stations, CO reported from 11 stations, against about 44 for PM. That is too thin to carry a reliable finding, so this edition reports PM2.5 and PM10 only, directly in micrograms per cubic metre. No composite AQI figure is published today. Percentages compare the same stations in both years; single-day observed spikes are never used as the headline.

Weather-corrected claims allowed (model skill adequate) · PM10: weather-corrected claims allowed (model skill adequate)

PM2.5: 35 of 39 stations above the WHO daily limit as observed; even after weather correction, 39 of 39 remain above it. PM10: 37 of 40 stations above the WHO daily limit as observed; even after weather correction, 40 of 40 remain above it. (Weather-model matched panel.)
