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 Sha Tin District data set draws from a single monitoring site that reports five key air‑quality constituents: nitrogen dioxide, ozone, PM10, PM2.5 and sulfur dioxide. All five pollutant measurements are present in the current feed, giving a complete picture of the major gases and particulate matter tracked by OpenAQ for this area.
Each pollutant’s most recent reading was recorded on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” freshness window. Because there is only one station contributing data, the dataset contains exactly five rows—one per pollutant—and every row carries a timestamp that is equally recent. The values show no internal variation: for each constituent the minimum, median and maximum are identical, meaning the single observation represents both the typical and extreme reading for the reporting period.
The measured concentrations are 43.7 µg/m³ for NO₂, 35.4 µg/m³ for O₃, 17.2 µg/m³ for PM10, 10.6 µg/m³ for PM2.5 and 2.1 µg/m³ for SO₂. With only one location feeding the system, the data capture is limited to conditions at that specific point in Sha Tin; variations across the broader district or at different times of day are not reflected here. Nonetheless, the dataset provides a current snapshot of all five pollutants, each reported with a single, up‑to‑date measurement from the same moment in time.
