What the data includes

The dataset for Sinsin includes five measured pollutants – nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulphur dioxide (SO₂) – all recorded at a single monitoring location (43N093 – SINSIN). In total there are five data rows, one for each pollutant, so the coverage is limited to this lone site.

The most recent observations are fairly fresh for four of the pollutants: NO₂, PM₁₀ and PM₂.5 were last updated on 2026‑02‑10 at 18:00 UTC, while O₃ was refreshed on 2026‑02‑09 at 10:00 UTC. SO₂ is older, with its latest reading from 2026‑01‑14 at 06:00 UTC, placing it in the “within 30 days” freshness category. Across the board each pollutant shows a single recorded value – NO₂ and O₃ both sit at 0.5 µg/m³ and 56.5 µg/m³ respectively, PM₁₀ is 0.771 µg/m³, and both PM₂.5 and SO₂ are reported as 0.0 µg/m³ – meaning the minimum, median and maximum are identical for each.

Because only one station contributes data, the numbers represent a very narrow snapshot of air quality in Sinsin. The uniformity of values (no spread between minimum and maximum) indicates that there is currently no observed variability within this limited dataset. Users should keep in mind that conditions can differ across neighbourhoods and times not captured by these five recent rows, especially given the older SO₂ measurement.
