Air quality today

The air quality in Jeongeup‑si is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 18.0 µg/m³ and a PM10 level of 24.0 µg/m³, based on 17 valid observations collected via OpenAQ.

These values 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 Jeongeup‑si air‑quality feed draws from three monitoring stations, each reporting a full set of six common pollutants: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10), fine particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO2). All the latest readings were recorded at 2026‑02‑10 18:00 UTC, so the data are uniformly fresh across every pollutant.

For CO the values range from a low of 0.30 ppm to a high of 0.75 ppm, with a median of 0.30 ppm; NO2 spans 0.0103–0.0169 ppm around a typical 0.013 ppm; O3 shows an unusually wide spread, from 0.0065 ppm up to an implausibly high 9999 ppm, with the median at 0.007 ppm, indicating that most recent measurements are low but one extreme outlier dominates the maximum. PM10 concentrations sit between 24 and 32 µg/m³, centering on 27 µg/m³, while PM2.5 varies from 18 to 27 µg/m³ with a median of 23 µg/m³. SO2 is measured in a narrow band of 0.0019–0.0025 ppm, the typical value being 0.002 ppm.

Because every station supplies data for all six pollutants, coverage across the city is consistent, but the distribution of values differs: particulate matter shows a modest spread, whereas ozone’s maximum suggests either a reporting error or an isolated spike. The uniform timestamp indicates that the dataset reflects conditions at a single recent moment rather than a rolling average, so while it captures the current state, it does not convey how concentrations may change throughout the day or across different neighborhoods.

Data notes

The data shown for Jeongeup‑si is based on 17 valid measurements and has been updated within 3 days, with the most recent refresh recorded at 2026‑02‑10T18:00:00+00:00. While these figures reflect the latest available monitoring, air quality can differ across neighborhoods and change throughout the day, so this snapshot may not represent conditions everywhere in the city at any given moment.
