The evidence

The daily residual: this year minus last year

■ Red: the de-weathered residual, weather removed. Above the zero line, pollution was higher than last year; below the zero line, it was lower.

Each point is a residual: that day's PM10 level minus the same period last year, after the model removes the effect of weather. The shaded band is the uncertainty around each day. Above the zero line means Delhi's air was genuinely worse than last year, and not merely unluckier with the wind; below it means genuinely cleaner. The run begins 30 May 2026.

A caution we publish daily

Gas readings carry documented unit-inconsistency at absolute levels (peer-reviewed international research, 2025); but this CO year-on-year uses the same stations + units as last year, so the DIRECTION of the rise is reliable. Today leads on PM2.5/PM10; gas is context only.
