What the data includes

The dataset for Mollet del Vallès includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), particulate matter 10 µm or smaller (PM₁₀) and particulate matter 2.5 µm or smaller (PM₂.₅). All of them are reported from a single monitoring location identified as MOLLET DEL VALLÈS (AP7 KM. 139), so the city’s air‑quality picture is based on one station row per pollutant, giving a total of five rows of data.

Each pollutant shows a single recorded value because the minimum, median and maximum are identical. NO registers at 3.0 µg/m³, NO₂ at 27.0 µg/m³, NOX at 30.0 µg/m³, PM₁₀ at 16.0 µg/m³ and PM₂.₅ at 11.0 µg/m³. The most recent update for every parameter is the same timestamp – 2026‑02‑10 03:00 UTC – which falls within the “updated within 7 days” freshness bucket, indicating that the data are currently fresh.

Because the coverage relies on a single measurement site, spatial variation across Mollet del Vallès cannot be captured in this set. The uniformity of the values (no spread between minimum and maximum) means there is no observable range for any pollutant at this location during the reporting period. While the timestamps are recent, the limited number of stations means that conditions elsewhere in the city may differ from what these figures show.
