Air quality today
The air quality in Villarejo de Salvanés is classified as Good today. The main pollutant identified is PM2.5, with a measured concentration of 1.0 µg/m³ based on three valid observations reported through OpenAQ.
These measurements indicate that fine particulate levels are within the reference value for this category. 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 Villarejo de Salvanés consists of a single monitoring station that reports four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM2.5). All measurements are expressed in micrograms per cubic metre (µg/m³).
The most recent data are very fresh for three of the compounds, with the last update logged on 2026‑02‑09 at 15:00 UTC for NO₂, O₃ and PM2.5. The NO value is older, recorded on 2024‑02‑29 at 00:00 UTC, and is flagged as “old data”. Across the four pollutants the observed values are identical to their minimum, median and maximum statistics, indicating no variation in the limited sample set: NO = 1.0 µg/m³, NO₂ = 6.0 µg/m³, O₃ = 67.0 µg/m³ and PM2.5 = 1.0 µg/m³. Because each pollutant has only one recorded reading, the inter‑percentile ranges (10th–90th) collapse to a single point.
With just one row of data, coverage is minimal; there are no older or unknown entries besides the single NO record, and the “old” flag applies only to that measurement. Consequently, while the timestamps for most pollutants suggest very recent monitoring, the overall picture is limited to a snapshot rather than a continuous series. Users should keep in mind that conditions can differ across neighborhoods and over time, and the current dataset does not capture such spatial or temporal variability.
