How air quality is measured

Recent particulate matter and ozone levels — a trailing-week air-quality average.

The clean-air score is the flip side of our air quality measure — 100 minus the raw air quality score — so a city with less of it scores higher.

Data sources: EPA AirNow and OpenAQ pollution readings (seven-day trailing average).
