What the data includes

The dataset for Sant Andreu de la Barca currently contains five recorded rows, one for each of the measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), particulate matter up to 10 µm (PM₁₀) and particulate matter up to 2.5 µm (PM₂.₅). All five rows are from a single monitoring station, so the coverage is limited to one location within the city.

Each pollutant shows a single reported value that also serves as its minimum, median and maximum for the period covered. NO registers at 3.0 µg/m³, NO₂ at 26.0 µg/m³, NOX at 30.0 µg/m³, PM₁₀ at 12.0 µg/m³ and PM₂.5 at 9.0 µg/m³. Because the data points are identical across the statistical fields (min, median, max, 10th‑percentile and 90th‑percentile), there is no observed variability in the measurements for this station.

The most recent update for every pollutant was recorded on 2026-02-10 03:00 UTC, which falls within a seven‑day freshness window. No older or unknown timestamps are present, indicating that the available data are relatively current despite the limited spatial coverage. Consequently, while the figures give an up‑to‑date snapshot for the specific monitoring point, they do not capture possible differences across other neighborhoods or times of day in Sant Andreu de la Barca.
