What the data includes

The air‑quality dataset for Stockton‑on‑Tees includes three measured pollutants – nitrogen dioxide (NO2), fine particulate matter (PM2.5) and coarse particulate matter (PM10). All data come from a single monitoring location, the Stockton‑on‑Tees Eaglescliffe site (UKA00535), so there is one row of observations for each pollutant.

The most recent readings were all recorded on 2026‑02‑10 at 20:00 UTC, meaning the latest values are less than a week old and therefore fairly fresh. For NO2 the dataset contains three separate records with values ranging from a low of 5.74 µg/m³ to a high of 29.0 µg/m³; the median measurement sits at 19.0 µg/m³, while the 10th and 90th percentiles are 8.39 µg/m³ and 27.0 µg/m³ respectively. PM2.5 is represented by two records, spanning a narrower band of 9.0 to 12.0 µg/m³; its median is 10.5 µg/m³ and the inter‑percentile range runs from 9.3 to 11.7 µg/m³. PM10 has only one entry, fixed at 16.0 µg/m³, so no spread can be shown for this pollutant.

Because the city’s data rely on a single monitoring station, coverage is limited: there are three rows in total and all belong to the same site, with no older or unknown‑timestamp entries. Consequently, while the recent measurements give a snapshot of current conditions at that location, they do not capture spatial variation across Stockton‑on‑Tees or longer‑term trends. Users should keep in mind that air quality can differ elsewhere in the city and may change after the last update.
