Air quality today

The air quality today in Gochang‑gun is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measured concentrations show a PM2.5 level of 15.0 µg/m³ and a PM10 level of 14.0 µg/m³.

Twelve valid measurements were recorded for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Gochang‑gun includes six measured 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). Data come from twelve individual rows that are grouped into two monitoring stations, both located in the town of 고창읍. Every pollutant record shows a “last updated” timestamp of 2026‑02‑10 17:00 UTC, which falls within the “updated within 7 days” freshness category, indicating that the most recent observations are all less than a week old.

Across the six pollutants the observed values span modest ranges. CO varies from a low of 0.21 ppm to a high of 0.29 ppm, with a median around 0.25 ppm; NO₂ runs between 0.0044 ppm and 0.0134 ppm, median roughly 0.009 ppm; O₃ is recorded from 0.0085 ppm up to 0.0154 ppm, median near 0.012 ppm. For the particulates, PM₁₀ values range from 7 µg/m³ to 14 µg/m³ (median 10.5 µg/m³) and PM₂.₅ from 10 µg/m³ to 15 µg/m³ (median 12.5 µg/m³). SO₂ is the most tightly clustered, moving between 0.0022 ppm and 0.0025 ppm with a median of about 0.00235 ppm.

Because all twelve rows are recent and come from only two sites in 고창읍, the data give a snapshot that is temporally fresh but spatially limited to one part of Gochang‑gun. The narrow spread for most pollutants suggests relatively stable conditions during the reporting period, while the slightly wider percentile range for PM₁₀ (7 µg/m³ to 13.3 µg/m³ at the 10th–90th percentiles) hints at modest variability in coarse particulate levels across the sampled times.
