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 current station data listed for this city is focused on particulate matter (PM). Only two pollutants are available – PM10 and PM2.5 – each reported from a single monitoring location in Woolston. The most recent reading for both pollutants was recorded on 2026-02-10 at 21:00 UTC, which falls within the “updated within 7 days” freshness category, indicating that the data is relatively current.
PM10 shows a value of 10.7881575 µg/m³ and PM2.5 a value of 3.2182071 µg/m³; both pollutants have identical minimum, median and maximum values because they come from only one observation. With just one station contributing data, there is no spread or variability to assess across the city, so the figures represent a snapshot rather than a comprehensive picture. Because coverage is limited to this single site, conditions elsewhere in Linwood‑Central‑Heathcote may differ, and additional monitoring points would be needed for broader insight.
