What the data includes

The dataset for Anjwa includes measurements of carbon monoxide, nitrogen dioxide, ozone, PM10, PM2.5 and sulfur dioxide. All six pollutants are represented, but each is drawn from a single monitoring record – the total row count is six, one per pollutant, all recorded at the same site in 신안군. The most recent timestamp for every parameter is 2026‑02‑10 18:00 UTC, which falls within the “updated within 7 days” freshness bucket, so the data are relatively current.

Across the board the reported values show no variation: carbon monoxide is consistently 0.33 ppm, nitrogen dioxide 0.0055 ppm, ozone 0.0323 ppm, PM10 15.0 µg/m³, PM2.5 16.0 µg/m³ and sulfur dioxide 0.0029 ppm. The minimum, median and maximum are identical for each pollutant, indicating that only a single measurement snapshot is available rather than a range of observations over time.

Because the coverage consists of just one station per pollutant, spatial diversity within Anjwa is limited; conditions elsewhere in the city may differ from those captured at 신안군. Nonetheless, the dataset provides a complete set of six common air‑quality indicators, all refreshed on the same recent date, giving a concise but narrow view of the current atmospheric composition for the city.
