Air quality today
The air quality in Derby today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).
Measurements show a PM2.5 reference value of 14.0 µg/m³ based on two valid observations recorded via OpenAQ. This indicates that the concentration of fine particulate matter is within the range associated with the Moderate category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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
Derby’s public air‑quality feed currently includes data from a single monitoring location, Derby St Alkmunds Way – UKA00630. At this site the dataset records two pollutants: nitrogen dioxide (NO2) and fine particulate matter (PM2.5). Both measurements were last updated on 2026‑02‑10 at 20:00 UTC, which falls within the “updated within 7 days” freshness window, indicating that the most recent values are relatively current.
The NO2 reading is a constant 23.0 µg/m³ across the minimum, median and maximum reported for this station, meaning there is no observed variation in the short‑term record. Likewise, PM2.5 shows a single value of 14.0 µg/m³ with identical min, median and max figures. Because only one row contributes data, the range for each pollutant collapses to a single point rather than a spread, so typical values cannot be compared against broader city‑wide variability.
With just one sensor providing both pollutants, coverage is limited to this specific street location; other parts of Derby are not represented in the current dataset. The freshness of the data is good—both pollutants have timestamps from the same recent update—but the lack of multiple stations means that spatial differences across the city cannot be captured at this time. Consequently, while the available numbers give a snapshot for Derby St Alkmunds Way, they do not reflect possible fluctuations elsewhere or over longer periods.

Data notes
The data shown for Derby reflects two valid measurements and was refreshed recently, being Updated within 3 days as of the last update on 2026‑02‑10T20:00:00+00:00. While this snapshot provides a current view of city‑wide air quality, conditions can differ across neighbourhoods and change throughout the day, so local variations may not be captured in these figures.
