What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only PM2.5 measurements are available from two monitoring rows in Auburn, Washington, and the most recent reading was recorded on 2026-02-11 00:00 UTC, which falls within the past seven days. One of the two rows provides a fresh observation while the other is older, indicating that coverage is limited to just a couple of points and not uniformly up‑to‑date across all locations.
Across the available data, PM2.5 values range from a minimum of 0.0 µg/m³ to a maximum of 2.6 µg/m³, with a median of 1.3 µg/m³. The lower decile sits at about 0.26 µg/m³ and the upper decile reaches roughly 2.34 µg/m³, showing that most recent measurements cluster in the low‑single‑digit range but can vary by a few micrograms per cubic metre. Because only two rows contribute data and one is dated, the snapshot may not capture the full spatial or temporal variability of air quality throughout Auburn.
