Air quality today
The air quality in Valdivia today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 13.0 µg/m³ and a PM10 level of 17.0 µg/m³, based on three valid observations.
Data are 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 Valdivia air‑quality feed contains data for six common pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO₂). All of these measurements come from a single monitoring station, so the dataset represents one row per pollutant.
The most recent values are fairly mixed in terms of freshness. The PM10, PM2.5 and SO₂ readings were updated on 2026‑02‑10 at 13:00, 12:00 and 11:00 UTC respectively, indicating data that is less than three days old. In contrast, the CO value dates back to 2021‑08‑20 21:00 UTC, NO₂ to 2020‑07‑20 23:00 UTC and O₃ to 2021‑07‑09 21:00 UTC, each of which is several years old. This means that while the particulate and sulfur measurements are current, the gas‑phase pollutants rely on older records.
Across the six pollutants the recorded concentrations show no variation within each series because only a single observation exists per pollutant. CO registers at 1242.4 µg/m³, NO₂ at 16.32 µg/m³, O₃ is reported as 0.0 µg/m³, PM10 at 17.0 µg/m³, PM2.5 at 13.0 µg/m³ and SO₂ at 12.62 µg/m³. Because the dataset consists of one row per pollutant, there is no spread or median range to compare; each value represents both the minimum and maximum recorded for that site.
Overall, the data set provides a complete list of key pollutants but its coverage is limited to a single location and includes recent measurements only for the particulate matter and sulfur dioxide. The older timestamps for CO, NO₂ and O₃ highlight that city‑wide conditions may differ from these isolated, dated readings, so any snapshot should be interpreted with that limitation in mind.

Data notes
The data shown for Valdivia reflects three valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 13:00 UTC. This snapshot provides a current view of citywide air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
