What the data includes

The Concón air‑quality record draws from ten measurement rows collected at three monitoring stations, covering the six key pollutants tracked by OpenAQ: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). For the most recent data, PM₂.₅, SO₂, and PM₁₀ have been updated within the last three days, with the latest timestamps on 2026‑02‑10 at 13:00 UTC. In contrast, CO, NO₂ and O₃ are based on older entries from 2021‑08‑20 at 21:00 UTC, so their values reflect conditions from more than four years ago.

Across the recent measurements, PM₂.₅ values range from a minimum of 20 µg/m³ to a maximum of 33 µg/m³, with a median of 31 µg/m³ and the central 80 % of observations falling between 22.2 and 32.6 µg/m³. SO₂ shows a narrower spread, varying from 15.7 to 25.02 µg/m³ (median 20.36 µg/m³), while PM₁₀ is reported as a single value of 35 µg/m³ for the latest row. The older CO data span a wide interval, from 301.31 up to 964.06 µg/m³ (median 632.69 µg/m³), and both NO₂ and O₃ are each represented by a single historic reading of 29.52 µg/m³ and 62.1 µg/m³ respectively.

Overall, the dataset provides recent coverage for three pollutants but relies on dated information for the other half, meaning that current conditions in Concón may differ from what is shown for CO, NO₂ and O₃. The limited number of stations (three) and the mix of fresh and old rows highlight uneven spatial and temporal representation, so readers should keep in mind that air‑quality can vary across neighborhoods and over time.

Data notes

The data shown for Concón reflects four valid measurements and is marked as Updated within 3 days, with the latest values recorded on 2026‑02‑10 at 13:00 UTC. This snapshot provides a recent view of ambient conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
