Air quality today

The air quality in Geoje‑si is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 22.0 µg/m³. In addition, the PM10 level is also reported at 22.0 µg/m³ based on 18 valid observations.

These values reflect the latest data shown via OpenAQ for Geoje‑si. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Geoje‑si air‑quality feed currently draws from three monitoring stations, each providing a single recent reading for the six pollutants tracked in this city: 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 observations were recorded at the same moment – 2026‑02‑10 18:00 UTC – so the dataset is uniformly fresh, with no rows older than seven days.

Across the three stations the measured values show a modest spread. CO ranges from 0.29 to 0.42 ppm, with a median of 0.38 ppm; NO₂ varies between 0.0078 and 0.0112 ppm (median 0.0091 ppm); O₃ is recorded from 0.0211 up to 0.0359 ppm (median 0.0272 ppm). For the particulates, PM10 values sit between 22 and 44 µg/m³ (median 35 µg/m³) while PM2.5 spans 22 to 34 µg/m³ (median 31 µg/m³). SO₂ is the lowest‑concentration gas, recorded from 0.0019 to 0.0032 ppm with a median of 0.003 ppm. The 10th and 90th percentiles for each pollutant confirm that most readings cluster near the medians, indicating limited extreme fluctuations in this snapshot.

Because only three stations contribute data, spatial coverage is relatively narrow; conditions can differ across other parts of Geoje‑si that are not directly represented here. Nevertheless, the uniform timestamp shows that the latest information is up to date for all six pollutants, offering a consistent picture of the city’s air quality at the time of measurement.

Data notes

The data shown reflects 18 valid measurements and is updated within 3 days, with the latest values recorded at 2026‑02‑10T18:00:00+00:00. While this snapshot provides a current overview of Geoje‑si’s air quality, conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these aggregate figures.
