What the data includes

The data for Barnsley includes five measured pollutants – nitrogen dioxide, ozone, PM10, PM2.5 and sulphur dioxide – all reported from a single monitoring location (Barnsley Gawber – UKA00353). Each pollutant has exactly one recorded value, so the dataset consists of five rows in total. All five rows are classified as recent, meaning the latest measurement for every pollutant was taken on 2026-02-10 at 20:00 UTC, which is within the past seven days.

Because each pollutant appears only once, the statistical spread is limited: the minimum, median and maximum values are identical for every substance. Nitrogen dioxide registers at 18.0 µg/m³, ozone at 31.0 µg/m³, PM10 also at 18.0 µg/m³, PM2.5 at 16.0 µg/m³ and sulphur dioxide at 2.0 µg/m³. The percentile‑10 and percentile‑90 figures match these same numbers, confirming that there is no observed variability in the current snapshot.

The dataset therefore provides a very narrow view of Barnsley's air quality – it reflects conditions at one site on a single recent date rather than a broader spatial or temporal picture. While the timestamps are fresh, the lack of multiple stations or repeated measurements means that variations across different neighbourhoods or over time are not captured here. Users should keep in mind that actual conditions elsewhere in Barnsley may differ from this point‑in‑time snapshot.

Data notes

The data shown for Barnsley is based on five valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10T20:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighbourhoods and throughout the day, so values may not represent every location or moment in the city.
