Air quality today

The air quality in Jinju‑si is currently assessed as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 29.0 µg/m³ and a PM10 level of 39.0 µg/m³, based on 24 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

Jinju‑si’s open‑air quality feed currently includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO₂). The dataset comprises 24 individual rows drawn from four monitoring stations, each providing a snapshot of the city’s atmosphere at a single point in time.

All six pollutants have recent observations: the newest timestamp for every parameter is 2026‑02‑10 18:00 UTC, which falls within the “updated within 7 days” freshness category. This means that, as of the latest pull, the data reflect conditions from just a few days ago rather than historic or stale records.

The values show modest variability across the city. CO ranges from 0.45 to 0.59 ppm with a median of 0.57 ppm; NO₂ spans 0.0183‑0.0287 ppm (median ≈ 0.025 ppm); O₃ is low, moving between 0.0004 and 0.009 ppm (median ≈ 0.003 ppm). Particulate matter exhibits a tighter band: PM10 varies from 34 to 44 µg/m³ (median ≈ 37.5 µg/m³) while PM2.5 stays between 25 and 29 µg/m³ (median ≈ 28.5 µg/m³). SO₂ is the least variable, recorded between 0.0023 and 0.0031 ppm (median ≈ 0.00255 ppm). For each pollutant the 10th‑percentile values sit close to the minima and the 90th‑percentile near the maxima, indicating that extreme readings are rare within this snapshot.

Because the dataset is limited to four stations, spatial coverage is not exhaustive; conditions can differ in neighborhoods without a sensor. Nonetheless, the uniform freshness across all six pollutants provides a coherent, up‑to‑date picture of Jinju‑si’s air quality at the time of collection.

Data notes

The data shown for Jinju‑si is based on 24 valid measurements and is Updated within 3 days, with the most recent values recorded at 2026-02-10T18:00:00+00:00. This snapshot reflects conditions measured across the city’s monitoring network but air quality can differ by specific location and time of day, so individual experiences may vary from the reported averages.
