Air quality today

The air quality today in Yeongam‑gun is classified as Moderate. The primary pollutant identified is PM2.5, fine particulate matter that contributes to the overall rating.

Measurements show a PM2.5 concentration of 31.0 µg/m³ and a PM10 level of 42.0 µg/m³ based on twelve valid observations reported through OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality feed for Yeongam‑gun draws from two monitoring sites that together provide twelve recent observations across 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). All of the latest readings were recorded on 2026‑02‑10 at 18:00 UTC, so the data are fresh within the past seven days for every pollutant.

CO values range from a low of 0.36 ppm to a high of 0.43 ppm, with a median of about 0.40 ppm; NO₂ spans 0.0129‑0.0232 ppm (median ≈0.018 ppm); O₃ shows the widest spread, from 0.0028 ppm up to 0.0227 ppm, centred around a median of roughly 0.013 ppm. Particulate matter is measured in micrograms per cubic metre: PM₁₀ varies between 42 and 46 µg/m³ (median ≈44 µg/m³) while PM₂.₅ runs from 31 to 35 µg/m³ (median ≈33 µg/m³). SO₂ is the smallest component, recorded between 0.0029 and 0.0035 ppm with a median near 0.0032 ppm.

Because each pollutant is reported by both stations, coverage is uniform across the six substances, but the number of observations per pollutant is modest – only twelve rows in total. The data set shows very little older or unknown information; every entry falls into the “updated within 7 days” category, indicating that the snapshot reflects recent conditions rather than historic averages. Nonetheless, with just two sites the measurements capture a limited spatial picture, so actual air quality can differ across other parts of Yeongam‑gun and at times outside the recorded moment.
