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 Islands District includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). All values come from a single monitoring station in Tung Chung, so the coverage consists of six rows of data, one for each pollutant.
Each pollutant shows an identical timestamp: the most recent reading was recorded on 2026-02-10 22:00 UTC, and the system flags indicate that this information was updated within the past three days. Because there is only one station, the statistical spread for every parameter is zero – the minimum, median, maximum and both the 10th‑percentile and 90th‑percentile values are the same as the single reported figure. CO registers at 770.0 µg/m³, NO₂ at 16.8 µg/m³, O₃ at 23.8 µg/m³, PM₁₀ at 17.6 µg/m³, PM₂.₅ at 13.0 µg/m³ and SO₂ at 0.6 µg/m³.
The data therefore provide a snapshot rather than a range of conditions across the district. With only one reporting site, spatial variation within Islands District cannot be assessed from this set, and any change over time would require additional observations beyond the single timestamp currently available.
