This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Cerro Navia is currently assessed as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 15.0 µg/m³ and a PM10 level of 62.0 µg/m³, based on two valid observations reported through 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 Cerro Navia air‑quality record contains data for five measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter up to 10 µm (PM₁₀) and particulate matter up to 2.5 µm (PM₂.₅). All of these come from a single monitoring station, so the dataset represents one row per pollutant.
The most recent observations are mixed in age. The CO, NO₂ and O₃ values were last updated on 2021‑08‑20 21:00 UTC, which classifies them as “old data” in the source system. By contrast, the PM₁₀ and PM₂.₅ measurements were refreshed on 2026‑02‑10 13:00 UTC, falling within the “updated within three days” category. This means that half of the pollutants have very recent readings while the other half reflect conditions from more than two years ago.
Across the five pollutants the recorded concentrations are all single values with no observed spread: CO is 1408.1 µg/m³, NO₂ is 112.99 µg/m³, O₃ is 1.61 µg/m³, PM₁₀ is 62.0 µg/m³ and PM₂.5 is 15.0 µg/m³. Because each pollutant has only one reported figure (minimum, median and maximum are identical), the dataset does not provide a range or variability for any of them.
Overall the coverage is limited to one monitoring location, so the data capture only the conditions at that specific point in Cerro Navia. The mix of very recent particulate‑matter readings and older gas‑phase measurements highlights an uneven temporal freshness across pollutants, and the lack of multiple stations means city‑wide variations cannot be assessed from this dataset alone.

Data notes
The data shown for Cerro Navia are based on two valid measurements and were updated within three days, with the latest reading recorded at 2026‑02‑10 13:00 UTC. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and throughout the day, so values may not represent the entire city’s current environment.
