Air quality today

The air quality in Okcheon‑gun is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 32.0 µg/m³ and a PM10 level of 29.0 µg/m³, based on six valid observations recorded by OpenAQ.

These values reflect the present conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Okcheon‑gun’s air‑quality feed draws from a single monitoring site that reports six key pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). The dataset contains twelve individual rows of observations, all tied to the same station in 옥천읍, and each measurement was last refreshed on 2026‑02‑10 at 18:00 UTC, well within the seven‑day freshness window that OpenAQ uses for recent data.

The recorded values show a fairly tight spread for most gases. CO ranges from 0.34 ppm to 0.41 ppm with a median of 0.375 ppm; NO₂ varies between 0.0072 ppm and 0.019 ppm, centering around 0.0131 ppm; O₃ is clustered tightly between 0.0197 ppm and 0.0207 ppm, median 0.0202 ppm. Particulate matter displays a broader distribution: PM₁₀ is constant at 29 µg/m³ across all rows, while PM₂.₅ spans from 16 µg/m³ up to 32 µg/m³ with a median of 24 µg/m³, indicating more variability in fine particles than in coarse ones. SO₂ remains low and stable, ranging from 0.0014 ppm to 0.0017 ppm, median 0.00155 ppm.

Because the data come from only one location, spatial coverage across Okcheon‑gun is limited; conditions elsewhere in the county may differ from those recorded at 옥천읍. Nevertheless, the dataset provides a recent snapshot of pollutant levels, with all six substances reported and timestamps uniformly fresh, allowing residents to see current concentrations even though broader geographic detail is not available.
