What the data includes

Dongducheon‑si’s open‑air quality feed contains six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), fine particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO₂). The dataset is built from 12 monitoring rows, each representing a recent observation at the same station in 보산동. All rows have been refreshed within the past seven days, with the most recent timestamp recorded on 2026‑02‑10 17:00 UTC for every pollutant.

The values show a modest spread across the city’s typical conditions. CO ranges from 0.29 to 1.03 ppm, with a median of 0.66 ppm; NO₂ varies between 0.0081 and 0.0243 ppm, centering around 0.0162 ppm; O₃ is observed from 0.0023 up to 0.0143 ppm, median 0.0083 ppm. Particulate matter shows higher absolute numbers: PM10 spans 27 µg/m³ to 82 µg/m³ (median 54.5 µg/m³) and PM2.5 ranges from 17 µg/m³ to 50 µg/m³ (median 33.5 µg/m³). SO₂ is the lowest‑concentration gas, recorded between 0.0025 and 0.0042 ppm with a median of about 0.00335 ppm.

Because every pollutant is reported from the same single location, spatial coverage across Dongducheon‑si is limited to that site, and any city‑wide interpretation should consider possible variation elsewhere. The dataset’s freshness is consistent—no rows are marked as old or unknown—and the latest measurements for each pollutant were taken at the same moment, providing a synchronized snapshot of air quality on 2026‑02‑10.
