What the data includes

The air‑quality record for Cardeñajimeno draws on a single monitoring station, so each pollutant is represented by one row of data. All six common pollutants are available: nitrogen monoxide (NO) at 1.0 µg/m³, nitrogen dioxide (NO₂) at 3.0 µg/m³, ozone (O₃) at 64.0 µg/m³, particulate matter ≤10 µm (PM₁₀) at 5.0 µg/m³, particulate matter ≤2.5 µg/m³ (PM₂.₅) at 4.0 µg/m³, and sulfur dioxide (SO₂) at 4.0 µg/m³. Each measurement is linked to the “BURGOS 4” sensor location.

The timestamps show that most values are recent: five of the six pollutants were last updated on 2026‑02‑09 between 12:00 and 15:00 UTC, indicating data refreshed within the past week. The NO reading is older, recorded on 2024‑01‑29 at 23:00 UTC, so it falls outside the “updated within 7 days” bucket. Overall, the dataset contains no entries classified as unknown or very old, and only one row (the NO value) is considered old.

Because there is just a single station, the range for each pollutant collapses to a single point – the minimum, median, and maximum are identical for every component. This means the data provide a snapshot rather than a spread of values across the city, and local variations in air quality cannot be captured from this source alone. Users should keep in mind that conditions may differ elsewhere in Cardeñajimeno or change between measurement times.
