Air quality today

The air quality in Coslada today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).

Measurements from eight valid observations show a PM2.5 reference value of 2.0 µg/m³ and a PM10 reference value of 4.0 µg/m³, as reported by OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Coslada draws on 14 recent observations collected from 2 monitoring stations. All five key pollutants—nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5)—are represented, but the freshness of the data differs between them. The most up‑to‑date measurements were taken on 2026‑02‑09 at 15:00 UTC for NO₂, O₃, PM10 and PM2.5, while the latest NO reading dates back to 2024‑02‑29 at 00:00 UTC and is therefore classified as older data.

Across the recent set, NO₂ shows a median concentration of 13.0 µg/m³ with values ranging from 12.0 to 49.0 µg/m³; the 10th percentile sits just above the minimum at 12.2 µg/m³ and the 90th percentile reaches 41.8 µg/m³, indicating a fairly tight spread around the median. Ozone is recorded at a single value of 50.0 µg/m³, which also represents both its minimum and maximum in this snapshot. Particulate matter levels are low: PM10’s median is 4.0 µg/m³ (range 2.0‑41.0 µg/m³) and PM2.5’s median is 2.0 µg/m³ (range 1.0‑17.0 µg/m³), with the lower ends of their distributions clustered near the minima. NO, by contrast, has a broader recent range of 2.0‑20.0 µg/m³ and a median of 11.0 µg/m³, but its data are older.

Overall, three‑quarters of the rows contain measurements updated within the past week, while one‑quarter (the NO entries) remain dated. This mix means that while recent snapshots give a clear picture for most pollutants, conditions for nitrogen monoxide may be less current and could differ across the city at any given moment.

Data notes

The dataset for Coslada includes eight valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑09 at 15:00 UTC; it is therefore considered updated within three days. These figures represent a snapshot of conditions captured by the monitoring network at that time. Keep in mind that air quality can vary across different neighborhoods and throughout the day, so values may differ from one location to another within the city.
