Air quality today

The air quality in Pradejón today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 3.0 and a PM10 reference value of 14.0, based on five valid observations collected via OpenAQ.

Overall conditions meet the criteria for a Good rating according to the provided assessment. 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 Pradejón draws on twelve recent observations collected from two monitoring stations. All seven common pollutants are represented: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). For most of them the newest data were logged on 2026‑02‑09, with timestamps at 14:00 UTC for NO₂, O₃ and SO₂ and at 03:00 UTC for PM₁₀ and PM₂.₅, showing that the latest measurements are less than a day old. CO and NO are exceptions; their most recent entries date back to 2020‑01‑13 and 2024‑01‑12 respectively, so those two pollutants rely on older records.

The recent values illustrate modest variability across the suite. NO₂ ranged from 10 µg/m³ to 14 µg/m³ with a median of 12 µg/m³; O₃ was tightly clustered between 46 µg/m³ and 47 µg/m³, median 46.5 µg/m³. PM₁₀ showed a broader spread, from 14 µg/m³ up to 25 µg/m³, median 19.5 µg/m³, while PM₂.₅ varied between 3 µg/m³ and 17 µg/m³, median 10 µg/m³. SO₂ was low but peaked at 4.2 µg/m³, with a minimum of 2.4 µg/m³ and median 3.3 µg/m³. The single CO reading stands at 390 µg/m³ and the lone NO value at 3.3 µg/m³.

Overall, half of the pollutant rows are fresh (updated within the last week), but three‑quarters of the dataset consists of recent data, while older entries dominate only for CO and NO. Because the station network is limited to two sites, spatial differences in Pradejón’s air quality may not be fully captured, especially for pollutants with outdated measurements. Users should keep in mind that conditions can change across neighborhoods and over time beyond what these snapshots show.

Data notes

The current dataset for Pradejón includes five valid measurements and is refreshed regularly, having been updated within the past three days (last update: 2026‑02‑09T14:00:00+00:00). These values represent a snapshot of ambient conditions at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
