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 Hwayang‑eup currently contains six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10), particulate matter 2.5 µm or smaller (PM2.5) and sulfur dioxide (SO₂). All values come from a single monitoring station in 화양읍, so the coverage is limited to one location rather than a network of sites across the city.
Each pollutant shows a single recorded value with no observed spread: CO is 0.54 ppm, NO₂ is 0.0126 ppm, O₃ is 0.0134 ppm, PM10 is 27.0 µg/m³, PM2.5 is 19.0 µg/m³ and SO₂ is 0.0025 ppm. Because the minimum, median, maximum and the 10th‑90th percentile values are identical for every pollutant, the data represent a snapshot rather than a range of measurements over time.
The most recent timestamp for all six pollutants is 2026-02-10 17:00 UTC, which falls within the “updated within 7 days” freshness category. This means the information is relatively current, but because it reflects only one moment from a single site, it does not capture possible variations elsewhere in Hwayang‑eup or changes that may occur later in the day. Users should keep in mind that local conditions can differ by place and time even when the latest data appear fresh.
