Air quality today

The air quality in Gimcheon is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 25.0 µg/m³ and a PM10 level of 32.0 µg/m³, based on 18 valid observations.

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

The dataset for Gimcheon includes six measured air‑quality pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀), particulate matter 2.5 µm or smaller (PM₂.₅) and sulfur dioxide (SO₂). All values come from three monitoring stations, giving a total of 18 rows of recent observations. The most recent update across the whole set was recorded on 2026‑02‑10 at 18:00 UTC, and every pollutant has data refreshed within the last seven days.

Across the three stations the CO readings range from 0.38 ppm to 0.42 ppm, with a median of 0.38 ppm; NO₂ varies between 0.007 ppm and 0.0126 ppm, centering around a median of 0.012 ppm. Ozone levels are recorded between 0.0293 ppm and 0.0369 ppm, with a typical value near 0.0361 ppm. For the particulate fractions, PM₁₀ spans 27 µg/m³ to 32 µg/m³ (median 30 µg/m³) while PM₂.₅ ranges from 21 µg/m³ to 25 µg/m³ (median 24 µg/m³). Sulfur dioxide is the lowest‑concentration gas, measured between 0.0019 ppm and 0.0033 ppm with a median of 0.0026 ppm.

The data show a fairly tight spread for each pollutant – the 10th to 90th percentile windows are narrow (for example, CO 0.380–0.412 ppm, PM₁₀ 27.6–31.6 µg/m³) – indicating limited variability among the three sites during the reporting period. However, the number of stations is modest; with only three locations, spatial differences within Gimcheon are not fully captured, so conditions can differ across neighborhoods despite the recent timestamps.
