Air quality today

The air quality today in Iksan‑si is classified as USG. The primary pollutant identified is PM2.5, with a reference concentration measured at 41.0 µg/m³. Additional monitoring shows a PM10 reference value of 50.0 µg/m³, based on 48 valid measurements reported through OpenAQ.

These values reflect the current state of ambient particulate matter in the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Iksan‑si’s OpenAQ feed includes six common air‑quality gases and particles: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO₂). The data come from eight monitoring stations, together contributing 66 individual measurement rows. Of those rows, 48 have been recorded within the last seven days, while another 18 are older than a week; none are marked as “today” or “unknown”. This mix of recent and slightly dated entries means that the snapshot reflects fairly current conditions but also contains some lagged observations.

Across the pollutants the most recent values (all logged at 2026‑02‑10 18:00 UTC) show CO peaking at 0.44 ppm in 여산면, NO₂ at 0.0144 ppm, O₃ at 0.0054 ppm, PM10 at 38.0 µg/m³, PM2.5 at 27.0 µg/m³ and SO₂ at 0.0031 ppm. The recorded ranges illustrate typical variability: CO spans from 0.31 to 0.45 ppm, NO₂ from 0.0043 to 0.0272 ppm, O₃ from 0.0029 to 0.0352 ppm, PM10 from 27 to 56 µg/m³ and PM2.5 from 12 to 41 µg/m³, while SO₂ varies between 0.0012 and 0.0033 ppm. Median values sit near the middle of these intervals (e.g., CO median 0.33 ppm, PM10 median 39 µg/m³), indicating that most recent readings are close to typical levels observed across the city.

Because all six pollutants are represented, users can compare gas concentrations with particulate matter in a single view, but the uneven freshness—only about three‑quarters of rows updated within a week—means some locations may not reflect the very latest changes. Consequently, while the dataset offers a broad spatial picture from eight stations, specific conditions can still differ by neighborhood and moment, especially where older measurements dominate.

Data notes

The data shown for Iksan‑si is based on 48 valid measurements and was refreshed within 3 days, with the most recent update recorded at 2026‑02‑10T18:00:00+00:00. While this snapshot reflects current monitoring conditions, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
