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 dataset for County Durham currently draws from a single monitoring location at Peterlee Claire Road. It provides measurements for five pollutants: PM1, PM2.5, relative humidity, temperature and particle counts (UM003). All five variables share the same most‑recent timestamp of 2026-02-10 21:00 UTC, meaning the newest data are just under two weeks old.
Because there is only one row in the source, each pollutant shows a single value that also serves as its minimum, median and maximum. PM1 registers at 21.32 µg/m³, while PM2.5 is recorded at 33.96 µg/m³. Relative humidity stands at 73.99 % and temperature at 8.47 °C. The particle concentration (UM003) is reported as 4 299.54 particles per cubic centimetre.
With only one monitoring site, the coverage does not capture spatial variation across County Durham; conditions can differ in other neighborhoods or towns. Likewise, the uniform timestamp indicates that no newer observations have been added since early February, so any changes after that point are not reflected in the current dataset.

Data notes
The data set for County Durham includes five valid measurements and was refreshed recently, with the latest update recorded on 10 February 2026 at 21:00 UTC; it is therefore considered “Updated within 3 days.” This snapshot reflects conditions at the time of sampling, but air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
