Air quality today

The air quality in Gimje‑si is currently classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 33.0 and a PM10 reference value of 26.0, based on twelve valid observations collected through OpenAQ.

These figures 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

The dataset for Gimje‑si contains measurements for six common air‑quality constituents: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). These values come from 18 individual rows of sensor data, representing two monitoring stations that together provide a snapshot of conditions across the city. The most recent update for each pollutant was recorded on 2026‑02‑10 at 18:00 UTC, so the newest observations are all less than a week old.

Across the six pollutants the observed ranges are fairly narrow. CO varies between 0.32 ppm and 0.46 ppm with a median of 0.37 ppm; NO₂ spans 0.004 ppm to 0.0151 ppm (median 0.0114 ppm); O₃ is recorded from 0.0115 ppm up to 0.0339 ppm (median 0.0128 ppm). For the particulate fractions, PM10 ranges from 23 µg/m³ to 26 µg/m³ (median 24 µg/m³) and PM2.5 from 16 µg/m³ to 33 µg/m³ (median 27 µg/m³). SO₂ shows the smallest spread, staying between 0.0013 ppm and 0.0014 ppm with a median of 0.0014 ppm.

The freshness profile indicates that twelve of the eighteen rows have been updated within the last seven days, while six rows are classified as older data. No entries are marked as “today” or “unknown,” suggesting that most measurements are reasonably current but that a minority may reflect conditions from earlier periods. Because the coverage relies on only two stations, spatial variation within Gimje‑si is not fully captured; local conditions can differ from the values reported here depending on neighborhood and time of day.

Data notes

The data shown reflects twelve valid measurements and was updated within three days, with the most recent update recorded at 2026‑02‑10T18:00:00+00:00. While these figures provide a current snapshot of air quality for Gimje‑si, conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
