What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only PM2.5 measurements are available, coming from four monitoring rows that together represent the full set of sensors reporting for Wiltshire. The most recent reading was recorded on 2026-02-10 20:32 UTC, and all entries fall within a seven‑day freshness window, indicating relatively up‑to‑date coverage across the city.

Across these stations PM2.5 values range from a low of 1.0 µg/m³ to a high of 27.63 µg/m³, with a median of 4.1 µg/m³. The 10th percentile sits at about 1.75 µg/m³ while the 90th percentile reaches roughly 20.75 µg/m³, showing that most observations cluster near the lower end but occasional spikes occur. One specific measurement records 3.5 µg/m³ at Stephenson Road. With four stations all reporting recent data, the dataset provides a snapshot of particulate levels, though conditions can still differ by location and time within Wiltshire.
