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).
