## Method

Select one metric (air_quality_pm25_annual_ug_m3), keep only numeric A/B rows with direct source URLs, sort ascending, and retain the original geographic fallback label.

## Boundary

This ranking is a source-backed reference. Read the source, geographic grain and observation date before comparing rows.
