What the data includes

Miranda de Ebro’s OpenAQ feed contains observations for seven pollutants – 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). The dataset is built from ten individual rows that come from two monitoring stations, so each pollutant is represented by at most one recent measurement.

The newest data are from 2026‑02‑09, with timestamps ranging between 12:00 UTC and 13:00 UTC for NO₂, SO₂, O₃, PM₁₀ and PM₂.₅. CO is the only value that dates back to 2016‑12‑19, and NO was last recorded on 2024‑01‑29, indicating that those two pollutants rely on older records while the others are refreshed within the past week.

Across the recent measurements the observed ranges are modest for most gases: NO₂ varies from a minimum of 8.0 µg/m³ to a maximum of 11.0 µg/m³ (median 9.5 µg/m³), SO₂ spans 2.0–3.0 µg/m³ (median 2.5 µg/m³) and O₃ is reported as a single value of 60.0 µg/m³. Particulate matter shows a wider spread; PM₁₀ ranges from 5.0 to 39.0 µg/m³ (median 22.0 µg/m³), while PM₂.₅ is recorded at a single point of 159.0 µg/m³. CO and NO each have only one historic entry, both fixed at 500.0 µg/m³ and 2.0 µg/m³ respectively.

Overall the dataset provides recent coverage for five of the seven pollutants but relies on outdated records for CO and NO, and there is no information classified as unknown or missing. Because the data come from just two stations, conditions can differ across neighborhoods and times that are not captured by these snapshots.

Data notes

The data shown for Miranda de Ebro are based on five valid measurements and have been updated within 3 days, with the latest refresh recorded at 2026‑02‑09T13:00:00+00:00. This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
