Readings

Monthly averages of every parameter with daily data, in the units OpenAQ reports.

The solid line averages every day OpenAQ published, as the mean of station monthly means; the dashed line averages full days only: at least 18 of 24 hours reported, not flagged by the provider, not negative. Averages across stations are not national figures or health-standard comparisons.

Opens on the latest month; scroll back for earlier years. A cell counts the days with at least one daily reading. A station stays on the grid after it stops; silence is not proof of closure.

Inactive and removed (0)

Stations that have gone quiet, most recent first
Every station is reporting
All stations reported within the last 30 days.

Silence is not proof of closure: a station can restart, and OpenAQ can return it again.

A partial day has fewer than 18 of its 24 hours reported; a day can be partial and flagged at once, so these overlap. Every station here carries a license in OpenAQ's records.
