Air quality today
The air quality in Samartín del Rei Aurelio is classified as Good today. The primary pollutant identified is PM10, with a measured concentration of 8.0 µg/m³ based on five valid observations reported through OpenAQ.
Overall conditions meet the Good category criteria, and the data set consists of five reliable measurements for the day. 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 air‑quality record for Samartín del Rei Aurelio includes six pollutant measurements collected from a single monitoring station. The dataset covers carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10) and sulfur dioxide (SO₂). For each of these substances the recorded values are identical across the minimum, median and maximum statistics, indicating that only one recent observation is available for every pollutant. CO registers at 100.0 µg/m³, NO at 2.0 µg/m³, NO₂ at 10.0 µg/m³, O₃ at 54.0 µg/m³, PM10 at 8.0 µg/m³ and SO₂ at 2.0 µg/m³.
All pollutants except NO have a “last updated” timestamp of 2026‑02‑09 15:00 UTC, which falls within the past week and therefore reflects very fresh data. The NO measurement is older, dated 2024‑01‑31 00:00 UTC, and is flagged as old data, showing an uneven recency across the set. Because there is only one monitoring row per pollutant, the dataset does not capture variability over time or space within the city; it provides a single snapshot rather than a range of observations.
Consequently, while the current figures give a clear picture of the most recent concentrations recorded at the lone station, they do not reveal any temporal trends or differences between neighborhoods. Users should keep in mind that air‑quality conditions can change throughout the day and across locations, and the limited number of rows means the available data represent only the specific moments when each sensor last reported.
