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 Xianxi Township dataset currently includes six pollutants—carbon monoxide, nitrogen dioxide, ozone, PM10, PM2.5 and sulfur dioxide—each reported from a single monitoring location identified as 彰化縣 - 線西. Because there is only one row of data for each pollutant, the station coverage is limited to that sole site, but all six entries have been refreshed within the past week; the most recent timestamp across the whole set is 2026-02-10 23:00 UTC.
For carbon monoxide the reading stands at 0.45 ppm, while nitrogen dioxide registers 0.032 ppm and ozone 0.001 ppm. Particulate matter concentrations are reported as 52.0 µg/m³ for PM10 and 33.0 µg/m³ for PM2.5, and sulfur dioxide is measured at 0.0025 ppm. Because each pollutant has only one recorded value, the minimum, median and maximum are identical, indicating no observed variability in this snapshot.
The data therefore give a clear but narrow picture of air quality in Xianxi Township: all pollutants are captured from a single point source, and the information is recent, having been updated within seven days. While the freshness of the timestamps ensures that the numbers reflect current conditions at that location, the lack of multiple stations means spatial differences across the township cannot be assessed from this dataset alone.
