What the data includes

The Danyang‑gun air quality record pulls data from three monitoring sites, giving a total of eighteen recent observations that have been updated within the last seven days. All six key 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)—are reported from the same timestamp of 2026‑02‑10 18:00 UTC, so the dataset reflects a single recent snapshot across the area.

For CO the values range from 0.64 to 1.76 ppm with a median of about 1.06 ppm, while NO₂ is measured between 0.0121 and 0.0314 ppm (median 0.0232 ppm). Ozone shows a narrower spread, from 0.0041 up to 0.018 ppm and a median near 0.0048 ppm. Particulate matter concentrations are reported in micrograms per cubic metre: PM10 varies from 38 to 48 µg/m³ with a typical value of 42 µg/m³, and PM2.5 ranges from 26 to 32 µg/m³, centering on 30 µg/m³. Sulfur dioxide is the least variable, staying between 0.0032 and 0.0068 ppm with a median of 0.0032 ppm.

Because every pollutant entry comes from the same three stations and shares the same recent timestamp, coverage across pollutants is uniform—there are no gaps where a substance is missing or significantly older than the others. The dataset therefore provides a consistent, up‑to‑date picture of air quality for Danyang‑gun as of early February 2026, though it reflects conditions at only a handful of locations and may not capture micro‑scale variations that can occur elsewhere in the county.
