What the data includes

The Yeonggwang 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). All data come from a single monitoring station, so the dataset consists of one row per pollutant. The most recent observation for each compound was recorded on 2026‑02‑10 at 17:00 UTC, meaning every value is fresh within the last seven days.

Across the six pollutants the observed ranges are fairly narrow. CO varies from a low of 0.25 ppm to a high of 0.32 ppm with a median of about 0.29 ppm; NO2 spans 0.0035‑0.0047 ppm (median 0.0041 ppm); O3 runs between 0.0213 and 0.0271 ppm (median 0.0242 ppm). Particulate matter shows a broader spread: PM10 values range from 18 to 30 µg/m³ (median 24 µg/m³), while PM2.5 is constant at 16 µg/m³ for the current reading. SO2 is measured between 0.0016 and 0.003 ppm, with a median of 0.0023 ppm.

Because only one station supplies data, spatial coverage across Yeonggwang is limited; conditions elsewhere in the city may differ from those recorded at the 영광읍 site. Nonetheless, the dataset provides up‑to‑date information for each pollutant, and the narrow interquartile ranges (10th to 90th percentiles) suggest relatively stable concentrations during the reporting period.
