What the data includes

The Taean‑gun air quality dataset currently contains six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO2). All values come from four monitoring stations, each providing a recent reading for every pollutant; the most recent update across the set was recorded on 2026‑02‑10 at 18:00 UTC, so the data are fresh within the past week.

Across the six pollutants the observed ranges show considerable variation. CO concentrations span from a low of 0.28 ppm to a high of 0.51 ppm, with a median around 0.38 ppm; NO2 varies between 0.0043 ppm and 0.0127 ppm, median roughly 0.01 ppm. Ozone levels range from 0.0104 ppm up to 0.0476 ppm, centering near 0.023 ppm. Particulate matter shows the widest spread: PM10 values are between 14 and 50 µg/m³ (median 26.5 µg/m³) while PM2.5 ranges from 3 to 35 µg/m³ (median 17 µg/m³). Sulfur dioxide is measured from 0.0014 ppm to 0.0059 ppm, with a median of about 0.003 ppm.

The dataset also reveals that the number of recent observations differs by pollutant. All six pollutants have at least one reading updated within the last seven days, but only CO and PM2.5 reach their maximum recorded values in the latest sample (0.51 ppm for CO and 35 µg/m³ for PM2.5). In contrast, NO2, O3 and SO2 are still below their recent peaks, indicating that short‑term fluctuations can be captured when stations report promptly. Overall, the four stations provide a fairly complete snapshot of Taean‑gun’s air quality at a single point in time, though conditions may vary across neighborhoods and over longer periods not covered by this immediate data window.
