Air quality today
The air quality in Vaqueiros is currently classified as Good. The main pollutant identified is PM10, and the reported reference value for this component is 0.7 µg/m³ based on a single valid measurement.
Data are shown via OpenAQ and reflect the latest available reading for the city. 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 Vaqueiros pulls information from a single monitoring station that reports five different pollutants: nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All five rows of data are classified as “recent”, meaning each measurement was recorded within the last seven days, with the most recent timestamp for every pollutant being 2026‑02‑10 21:00 UTC.
Only one of the pollutants has a reported concentration value. PM₁₀ shows a consistent reading of 0.7 µg/m³ across the whole dataset, which is also the median, minimum and maximum observed value, indicating no variation in this metric for the period covered. The other four pollutants – NO₂, O₃, PM₂.5 and SO₂ – all carry a placeholder value of -1.0 µg/m³, signalling that no valid concentration data were available from the station at the time of collection.
Because the coverage consists of a single monitoring location, the spatial representation of air quality across Vaqueiros is limited to that point. The freshness of the data is good overall, with every row updated within the past week, but the lack of actual measurements for four of the five pollutants means the picture remains incomplete. Users should keep in mind that conditions can differ elsewhere in the city and at other times, especially for those pollutants where no values were recorded.

Data notes
The current reading for Vaqueiros is based on a single valid measurement and was updated within 3 days, with the latest data recorded at 2026‑02‑10T21:00:00+00:00. This snapshot reflects conditions at one monitoring point and moment in time; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured by this single observation.
