This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Aia today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
Measurements from four valid monitoring points show a PM2.5 reference value of 2.0 µg/m³ and a PM10 reference value of 5.0 µg/m³. Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Aia contains a single monitoring location – the PAGOETA station – which supplies readings for six common air‑quality pollutants: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and particulate matter ≤2.5 µm (PM₂.₅). Because only one row is present, the coverage across the city is limited to this point rather than a network of sites.
All six pollutants have recent measurements recorded on 2026‑02‑09, except for NO which was last updated on 2024‑01‑16. The CO value is consistently reported as 340 µg/m³, with no variation in minimum, median or maximum – the same single figure appears across the entire data slice. NO₂, O₃, PM₁₀ and PM₂.5 also show a single recorded value each (2 µg/m³, 75 µg/m³, 5 µg/m³ and 2 µg/m³ respectively), indicating that only one observation is currently available for these pollutants. The NO reading of 1 µg/m³ is older by more than two years, which makes it the least up‑to‑date element in the set.
Because each pollutant’s statistics consist of a single point, there is no observable spread or range; the reported minimum, median and maximum are identical for every compound. This uniformity reflects the limited temporal depth of the data rather than stable environmental conditions. Consequently, while the dataset provides a snapshot of current concentrations at PAGOETA, it does not capture variability across different neighborhoods or over time, and users should keep in mind that air‑quality conditions elsewhere in Aia may differ from those recorded at this solitary site.

Data notes
The current dataset for Aia includes four valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑09T15:00:00+00:00. These figures represent a recent snapshot of ambient conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
