How to read this report
Use the compatible published metric air_quality_pm25_annual_ug_m3, keep one machine-readable unit family with direct source URLs, and sort ascending.
- Compare the displayed value, unit, source date and geographic grain together.
- A city label does not change a regional observation into a city measurement.
