What the data includes

The OpenAQ feed for Manchester currently contains data from nine monitoring stations spread across 57 individual rows. All eight listed pollutants—nitrogen dioxide (NO₂), ozone (O₃), particulate matter 1 µm (PM₁), particulate matter 10 µm (PM₁₀), particulate matter 2.5 µm (PM₂.5), relative humidity, sulfur dioxide (SO₂) – although no recent SO₂ values are present in the rows – temperature and ultra‑fine particle count (UM003) – are represented to varying degrees. The most recent timestamps cluster around 2026-02-10 20:00 UTC to 21:00 UTC, with PM₂.5, temperature, PM₁, relative humidity, and UM003 all last updated at 2026-02-10 21:00 UTC, while NO₂, O₃ and PM₁₀ were refreshed a hour earlier at 2026-02-10 20:00 UTC. Overall freshness is mixed: 19 rows are known to be less than three days old, five are between three and seven days, 25 are older than thirty days, eight have an unknown age, and the remaining rows fall into other categories.

Across the recent data, PM₂.5 values range from a low of 0 µg/m³ up to 25.3 µg/m³ with a median of 9 µg/m³; temperature spans 10.2 °C to 25.3 °C (median 22.9 °C); PM₁₀ varies between 1.7 µg/m³ and 14.6 µg/m³ (median 11 µg/m³). Relative humidity shows a broad spread from 26.6 % to 71.9 % (median 54 %). The ultra‑fine particle count (UM003) is especially variable, ranging from about 56 particles/cm³ to over 2,300 particles/cm³ with a median near 795 particles/cm³. In contrast, NO₂ and O₃ have very narrow recent ranges – NO₂ between 22 µg/m³ and 27 µg/m³ (median 24.5 µg/m³) and O₃ from 16 µg/m³ to 29 µg/m³ (median 22.5 µg/m³). Because the dataset includes both very recent and considerably older rows, conditions reported here can differ noticeably across locations and times within Manchester.

Data notes

The dataset for Manchester includes 24 valid measurements and is refreshed Updated within 3 days, with the most recent values recorded on 2026‑02‑10T21:00:00+00:00. These figures represent a snapshot of current conditions; air quality can differ across neighbourhoods and change throughout the day, so local variations may not be captured in this summary.
