What the data includes

The air‑quality dataset for Torrejón de Ardoz contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). These values come from 14 rows of sensor data, but only two distinct monitoring stations are represented in the current collection.

The most recent measurements were recorded on 2026‑02‑09 at 15:00 UTC for NO₂, O₃, PM₁₀ and PM₂.5, while the latest NO reading dates back to 2024‑02‑28 at 23:00 UTC, indicating that nitrogen monoxide data are older than the other pollutants. Across the recent set (updated within the last seven days), NO₂ shows a minimum of 20 µg/m³, a median of 21 µg/m³ and a maximum of 55 µg/m³; O₃ is recorded at a single value of 58 µg/m³, which also represents its median and upper bound. PM₁₀ values range from 6 to 32 µg/m³ with a typical level around 7 µg/m³, while PM₂.5 spans 1 to 14 µg/m³ and is usually close to 1 µg/m³. The older NO data vary between 1 and 4 µg/m³, centered near 2.5 µg/m³.

Overall, the dataset provides a recent snapshot for four of the five pollutants, but coverage is uneven because only two stations contribute data and one pollutant (NO) relies on information that is nearly two years old. Consequently, while the available numbers give an idea of current conditions at those sites, they do not capture the full spatial or temporal variability that may exist across Torrejón de Ardoz.
