This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality today in Concepción is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).
Measurements from three valid observations show a PM2.5 reference value of 13.0 µg/m³ and a PM10 reference value of 25.0 µg/m³. 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 Concepción includes five monitoring rows that together report on carbon monoxide (CO), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO₂). All five pollutants are represented, but the timing of their most recent measurements differs markedly. The CO and O₃ values were last refreshed on 2021‑08‑20 19:00 UTC, which the source flags as “old data”. In contrast, PM10, PM2.5 and SO₂ each have a latest timestamp of 2026‑02‑10 13:00 UTC and are labelled as updated within three days.
Because each pollutant appears in only one row, the reported figures show no variation across observations – the minimum, median and maximum values are identical for every substance. CO registers at 820.98 µg/m³, O₃ at 37.88 µg/m³, PM10 at 25.0 µg/m³, PM2.5 at 13.0 µg/m³ and SO₂ at 11.69 µg/m³, all measured at the Kingston College site. This uniformity indicates that the current snapshot reflects a single point in space rather than a city‑wide average.
The mix of timestamps highlights an uneven data freshness: three pollutants provide very recent readings while two rely on information that is more than two years old. Consequently, the dataset offers only limited insight into how air quality may vary across different neighborhoods or over time in Concepción. Users should keep in mind that conditions can differ by location and moment, and the available numbers represent a narrow temporal and spatial slice of the city’s atmosphere.

Data notes
The data shown for Concepción reflects three valid measurements and is updated within 3 days, with the most recent reading recorded at 2026‑02‑10T13:00:00+00:00. This snapshot provides a brief overview of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
