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 Gijón air‑quality dataset 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 sulphur dioxide (SO₂). These measurements come from 57 recent‑time rows collected at eight monitoring stations across the city, giving a fairly broad spatial picture of ambient conditions.

All pollutants except NO have data that were updated within the last seven days, with the most recent timestamps recorded on 2026‑02‑09 15:00 UTC. The oldest entry in the set is for NO, which dates back to 2024‑01‑31 00:00 UTC and is therefore classified as “old data”. Typical values show a modest spread: NO₂ ranges from 18 µg/m³ up to 41 µg/m³ with a median of 32 µg/m³, while O₃ varies between 1 µg/m³ and 46 µg/m³ (median 26.5 µg/m³). PM₁₀ values are generally low, from 6 to 66 µg/m³ with a median of 12.5 µg/m³, and the highest recent reading for PM₂.₅ is 9 µg/m³ (median 6 µg/m³). SO₂ remains near background levels, between 1 and 7 µg/m³ (median 5 µg/m³), and CO shows a broader range from 100 to 640 µg/m³ (median 370 µg/m³).

Because the dataset includes only one recent entry for NO and several older rows, coverage is uneven across pollutants. The majority of the data are fresh, but the presence of old or missing timestamps means that conditions can differ between locations and times not captured here. Users should keep in mind that the snapshot reflects measurements taken at specific stations on the dates listed, and city‑wide air quality may vary outside those points.

Data notes

The dataset for Gijón includes 36 valid measurements and is Updated within 3 days, with the most recent data recorded on 2026‑02‑09T15:00:00+00:00. This information reflects a snapshot of conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
