Air quality today

The air quality today in Namwon‑si is classified as USG. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 41.0 µg/m³ and a PM10 level of 49.0 µg/m³, based on twelve valid observations reported through OpenAQ.

These values reflect the current monitoring results for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Namwon‑si contains measurements for six common air 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 values come from a total of twelve recorded rows, drawn from two monitoring stations that report the same set of pollutants.

Every pollutant entry was last refreshed on 2026‑02‑10 at 18:00 UTC, which falls within the “updated within 7 days” freshness window, so the data reflects very recent conditions across the city. The recorded concentrations show a modest spread for each gas and particle type. CO ranges from a low of 0.26 ppm to a high of 0.46 ppm with a median near 0.36 ppm; NO₂ varies between 0.003 ppm and 0.0159 ppm, centering around 0.009 ppm; O₃ spans 0.0036‑0.0417 ppm with a median of about 0.023 ppm. Particulate matter shows broader variation: PM₁₀ values run from 10 µg/m³ up to 49 µg/m³, the middle point being 29.5 µg/m³; PM₂.₅ ranges from 5 µg/m³ to 41 µg/m³ with a median of 23 µg/m³. SO₂ is the most tightly clustered, recorded between 0.0029 ppm and 0.0033 ppm, median roughly 0.0031 ppm.

Because each station reports all six pollutants, coverage across contaminant types is even, but the limited number of stations means spatial detail is coarse; conditions can differ in neighborhoods not directly represented by the two sites. The data’s freshness ensures that these snapshot values are current, yet they capture only a single moment in time and should be interpreted as such.

Data notes

The data shown for Namwon‑si reflects twelve valid measurements and is updated within three days, with the most recent reading recorded at 2026‑02‑10T18:00:00+00:00. This snapshot provides a current view of citywide air quality, but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these aggregate figures.
