What the data includes

The dataset for Haenam‑gun contains measurements from a single monitoring site located in 해남읍. All six key pollutants tracked by OpenAQ are represented: carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), ozone (O₃, written as O3), particulate matter up to 10 µm (PM10), fine particulate matter up to 2.5 µm (PM2.5, written as PM25), and sulfur dioxide (SO₂). Each pollutant has exactly one recorded value because the data set consists of a single row per parameter.

All observations were last updated on 2026‑02‑10 at 17:00 UTC, which falls within the “updated within 7 days” freshness category. Because there is only one station, the reported minimum, median and maximum values are identical for every pollutant, indicating no observed spread in this snapshot. CO registers at 0.27 ppm, NO₂ at 0.0071 ppm, O₃ at 0.0278 ppm, PM10 at 21.0 µg/m³, PM2.5 at 17.0 µg/m³, and SO₂ at 0.0026 ppm.

The limited coverage means the data reflects conditions only at the 해남읍 location and cannot capture spatial variations across Haenam‑gun. While the timestamps are recent, the single‑point nature of the record provides a narrow view; any changes in air quality elsewhere in the county or over short time intervals would not be reflected here. Consequently, users should keep in mind that the figures represent a snapshot from one site rather than a comprehensive picture of the entire area.

Data notes

The data shown for Haenam‑gun is based on six valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10T17:00:00+00:00. This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
