Air quality today
The air quality today in Dacheng Township is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 46.0 µg/m³. In addition, the PM10 level is recorded at 80.0 µg/m³ based on six valid observations.
These measurements are provided through OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Dacheng Township contains a single monitoring station that reports six common air‑quality gases and particles: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All six pollutants are present, but the coverage is limited to just one row of data, so spatial variation within the township cannot be assessed from this source.
The most recent measurements for every pollutant were recorded on 2026‑02‑10 at 23:00 UTC, meaning the entire set is fresh within the last seven days. Each pollutant shows a single reported value with no observed spread: CO is consistently 0.4 ppm, NO₂ remains at 0.021 ppm, O₃ at 0.003 ppm, PM₁₀ at 80.0 µg/m³, PM₂.5 at 46.0 µg/m³ and SO₂ at 0.0017 ppm. Because the minimum, median, maximum, 10th percentile and 90th percentile are identical for every metric, the data reflect a snapshot rather than a range of conditions.
With only one station contributing, the dataset cannot capture differences across neighborhoods or times of day. The uniform timestamps indicate that all pollutants were logged simultaneously, providing a synchronized view but offering no insight into temporal trends. Consequently, while the figures give a clear picture of the air‑quality status at the moment of measurement, they do not reveal how conditions may vary elsewhere in Dacheng Township or change over longer periods.
