What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only one pollutant—PM2.5—is reported from five monitoring locations in Corvallis, Oregon. The most recent measurement was recorded on 2026-02-11 00:00 UTC, and four of the five rows have timestamps within the past seven days, while one row is older than that window. Across these stations, PM2.5 values range from a low of 3.2 µg/m³ to a high of 6.1 µg/m³, with a median reading of about 5.16 µg/m³. The 10th percentile sits near 3.9 µg/m³ and the 90th percentile close to 6.0 µg/m³, indicating that most recent observations cluster within a relatively narrow band.

Because the dataset includes only PM2.5 and covers five rows, coverage of other pollutants is absent, limiting the breadth of air‑quality insight for Corvallis. Although four stations provide fresh data, the single older entry means the overall picture may not capture all local variations at any given moment. Users should keep in mind that conditions can differ across neighborhoods and times, and the available numbers reflect only the specific locations and timestamps currently reported.
