What the data includes

The Vale of White Horse dataset currently contains six measured pollutants – PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003 – all recorded at three monitoring stations. In total there are eighteen rows of data across these stations, giving a modest but usable snapshot of local air quality.

Freshness varies by pollutant. The most recent readings for PM1, PM2.5, relative humidity, temperature and UM003 were taken on 2026‑02‑10 at 21:00 UTC, while the latest PM10 value dates back to 2025‑01‑13 at 23:00 UTC, making it the oldest of the set. Median values show that typical fine particulate concentrations sit around 4.87 µg/m³ for PM1 and 8.93 µg/m³ for PM2.5, with a broader spread for PM10 where the median is 32.37 µg/m³ but individual measurements range from about 19.49 to 34.59 µg/m³. Relative humidity hovers near 65 % (median 65.22 %) and temperature stays around 13.6 °C (median 13.58 °C). The particle count UM003 reaches a median of roughly 766 particles/cm³, with observed values spanning from about 532 to 963 particles/cm³.

Because the dataset includes only three stations, conditions can differ across the wider Vale of White Horse area and the limited spatial coverage means the figures represent specific points rather than the entire district. Additionally, the older PM10 timestamp indicates that not all pollutants are updated with the same frequency, so recent changes in coarse particulate levels may be under‑represented compared with the more current fine‑particle and meteorological data.
