Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The data for Warrington includes three measured pollutants – nitrogen dioxide (NO2), particulate matter up to 10 µm in diameter (PM10) and fine particulate matter up to 2.5 µm (PM2.5). All values come from a single monitoring station, identified as Warrington - UKA00538, so the coverage represents one specific location within the town rather than a network of sites.
Each pollutant shows a single recorded value because the minimum, median and maximum are identical. The most recent reading for every compound was taken on 2026‑02‑10 at 20:00 UTC, which falls into the “updated within 7 days” freshness category. NO2 is reported at 21.0 µg/m³, PM10 at 13.0 µg/m³ and PM2.5 at 8.0 µg/m³. Because there is only one row of data, there is no spread to describe; the range for each pollutant is effectively zero (the same figure appears as both the low‑end and high‑end of the distribution).
With just one monitoring point, the dataset cannot capture spatial variations across different neighbourhoods or streets in Warrington. The timestamps are recent, so the information reflects conditions at a specific moment rather than long‑term trends. Users should keep in mind that air quality can change throughout the day and differ between locations, and the single‑station snapshot provides only a limited view of the town’s overall atmospheric state.
