Air quality today
The air quality in Los Corrales de Buelna is classified as Good today. The main pollutant identified is PM10, and the reference value for this particle size is 12.0 µg/m³. Four valid measurements were recorded to support this assessment.
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 air‑quality record for Los Corrales de Buelna is built from a single monitoring station, so each pollutant is represented by one row of data. The dataset includes five measured species: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10) and sulfur dioxide (SO₂).
The most recent measurements were all taken on 2026‑02‑09 at 15:00 UTC for NO₂, O₃, PM10 and SO₂, showing that the bulk of the data is fresh within the last seven days. The only older entry is for NO, recorded on 2024‑02‑04 at 23:00 UTC, which means that nitrogen monoxide information is more than two years out of date while the other pollutants reflect current conditions.
Across the five pollutants the values are single points rather than ranges: NO is reported as 0.0 µg/m³, NO₂ as 17.0 µg/m³, O₃ as 33.0 µg/m³, PM10 as 12.0 µg/m³ and SO₂ as 4.0 µg/m³. Because each pollutant has only one observation, the minimum, median and maximum are identical, indicating no observed variability in this snapshot. The dataset therefore provides a very narrow view of air quality – it captures the latest point for each contaminant but does not show how concentrations change over time or differ across locations within the municipality. Users should keep in mind that conditions can vary throughout the day and between neighborhoods, and the single‑station coverage may miss those spatial differences.
