Today · 22 July 2026

Delhi's air looks -14 points vs last year on the meter, but that is the weather's work. Remove it, and the city is +22 points worse than last year. The improvement belongs to the weather, not to policy. Today's reading itself is weather-flattered by about 31 points.

Analysis window: 10 AM 21st July to 10 AM 22nd July
Baseline: YoY baseline: avg of 15th Jul - 29th Jul 2025 (same +/-7 days), matched stations
A caution we publish daily: Gas data carries documented unit-inconsistency (peer-reviewed international research, 2025); we lead on the reliable PM2.5/PM10.
