What the data includes

The Buyeo‑gun data set contains a single monitoring location in 부여읍, so all six standard pollutants are represented by one row each. Carbon monoxide is reported at 0.65 ppm, nitrogen dioxide at 0.019 ppm, ozone at 0.0066 ppm, particulate matter 10 µg/m³ at 48.0 µg/m³, particulate matter 2.5 µg/m³ at 20.0 µg/m³, and sulfur dioxide at 0.0044 ppm. Because there is only one station, the minimum, median and maximum values are identical for each pollutant, indicating no observed variation within this data set.

All measurements were last updated on 2026‑02‑10 at 18:00 UTC, which places every reading in the “updated within 7 days” freshness bucket. This means the most recent data for Buyeo‑gun is less than a week old, but there are no older or unknown timestamps to show longer‑term trends. With only one reporting site, coverage across the municipality is limited; conditions elsewhere in Buyeo‑gun may differ from those captured at this single point.

Because each pollutant has just one recorded value, the data cannot reveal any spread or temporal changes. The reported figures give a snapshot of current concentrations but do not provide insight into variability over time or space within the county. Users should keep in mind that air quality can fluctuate across different neighborhoods and days, and the present dataset reflects only the conditions at the 부여읍 monitoring location on the specified date and time.
