Each square is a month's mean PM2.5 in US AQI from Deuchendorf's measured days, with its place on that month's world ranking under it. A month has a mean once 70% of its days are measured, the rule the monthly rankings use; under that, the square gives the days measured. Each square opens that month's ranking with Deuchendorf marked; each year, the year's.

Months without a mean, and why

1 month
MonthWhy

A day counts once 18 hours of it are measured; a month needs 70% of its days.
