Air quality today
The air quality in Valdemoro today is classified as Good. The primary pollutant identified is PM2.5, with measurements indicating a concentration of about 1.0 µg/m³.
Six valid observations were recorded for the current assessment period, confirming the Good category and the presence of fine particulate matter as the main component. 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 Valdemoro air‑quality dataset contains measurements for four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM₂.5). Data come from a total of eleven rows collected at two monitoring stations within the municipality, giving a modest spatial coverage that captures conditions at only a few points across the city.
The most recent observations for NO₂, O₃ and PM₂.5 were recorded on 2026‑02‑09 at 15:00 UTC, while the latest NO reading dates back to 2024‑02‑29 at 00:00 UTC, indicating that nitrogen monoxide data are considerably older than the other pollutants. For the three newer series, the median values are 5 µg/m³ for NO₂, 61 µg/m³ for O₃ and 2 µg/m³ for PM₂.5, with minimums of 4, 3 and 1 µg/m³ respectively. The maximum recorded levels reach 48 µg/m³ for NO₂, 67 µg/m³ for O₃ and 18 µg/m³ for PM₂.5, showing a broader spread especially for ozone where the 90th percentile sits at about 66 µg/m³ compared with a 10th percentile of roughly 15 µg/m³.
Overall, most of the data are fresh—seven out of eleven rows were updated within the last seven days—but the older NO measurements and the limited number of stations mean that the picture is incomplete. Conditions can differ across neighborhoods and times of day, so while the available figures give a snapshot of recent air quality in Valdemoro, they do not capture the full variability that may exist throughout the city.
