Air quality today
The air quality in Arrúbal today falls within the Good category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 3.0 µg/m³ and a PM10 reference value of 10.0 µg/m³, based on six valid observations.
These figures indicate that the concentrations of particulate matter are within the limits defined for this assessment. 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 Arrúbal draws on 13 recent data rows collected at two monitoring stations, covering the seven pollutants measured in the OpenAQ network: carbon monoxide (CO), nitrogen oxides (NO and NO₂), ozone (O₃), particulate matter 10 µm (PM₁₀) and 2.5 µm (PM₂.₅), and sulfur dioxide (SO₂). All pollutants except NO have been updated within the past week; the newest timestamps range from 2026‑02‑09 03:00 UTC for PM₁₀ and PM₂.₅ to 2026‑02‑09 14:00 UTC for CO, while the lone NO reading dates back to 2024‑01‑12 00:00 UTC.
Across the recent measurements, CO values span from a low of 110 µg/m³ to a high of 240 µg/m³ with a median of 175 µg/m³, indicating a relatively wide spread. NO₂ shows a narrower band, ranging between 3.1 and 12 µg/m³ (median 7.55 µg/m³), and O₃ varies from 33 to 43 µg/m³ (median 38 µg/m³). Particulate matter is also well represented: PM₁₀ ranges from 10 to 23 µg/m³ (median 16.5 µg/m³) and PM₂.₅ from 3 to 13 µg/m³ (median 8 µg/m³). SO₂ measurements are low, between 1.3 and 2.3 µg/m³ with a median of about 1.8 µg/m³.
The dataset is therefore recent for most pollutants, but the NO figure is outdated, highlighting an uneven temporal coverage across the suite of contaminants. With only two stations feeding the record, spatial variation within Arrúbal cannot be captured in detail; conditions may differ between neighborhoods and times not represented by these rows.

Data notes
The data shown for Arrúbal reflects six valid measurements and is updated within three days, with the most recent reading recorded on 2026‑02‑09 at 14:00 UTC. This snapshot provides a current view of ambient air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
