Air quality today

The air quality in Suncheon‑si is currently rated as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measured concentrations show a PM2.5 value of 17.0 µg/m³ and a PM10 level of 19.0 µg/m³.

A total of 30 valid measurements were recorded for today’s assessment. Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Suncheon‑si’s OpenAQ feed currently includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO₂). The dataset comprises 42 individual rows drawn from five monitoring stations, each reporting the same set of pollutants.

All six pollutants have recent data: the most recent timestamp for every parameter is 2026‑02‑10 18:00 UTC, which falls within the “updated within 7 days” freshness bucket. CO values range from a low of 0.17 ppm to a high of 0.26 ppm, with a median of 0.23 ppm; NO₂ spans 0.0031‑0.0529 ppm (median 0.0041 ppm); O₃ varies between 0.0308‑0.0736 ppm (median 0.0361 ppm). For the particulate matter metrics, PM10 shows a broad spread from 8 µg/m³ up to 178 µg/m³, median 19 µg/m³, while PM2.5 ranges from 6‑34 µg/m³ with a median of 9 µg/m³. SO₂ is the most tightly clustered, ranging only from 0.002‑0.0036 ppm (median 0.0031 ppm).

The data illustrate that particulate matter exhibits considerably wider variability than the gaseous pollutants, suggesting spatial or temporal differences across the city’s monitoring sites. Despite the modest number of stations, every pollutant is represented at each location, providing a uniform but limited snapshot of air quality. Because the dataset reflects conditions as of early February 2026, actual concentrations may differ at other times of day or in unmonitored neighborhoods.
