Air quality today

The air quality in Muan is currently classified as Moderate. The primary pollutant identified is PM2.5, fine particulate matter that is measured alongside larger particles. Recent observations show a PM2.5 concentration of 23.0 µg/m³ and a PM10 level of 33.0 µg/m³, based on six valid measurements collected through OpenAQ.

These values reflect the present state of ambient air in the city without implying any health implications. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Muan contains measurements from a single monitoring site located in 무안읍, and it reports six common air‑quality 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). All values are drawn from the same most‑recent observation time, recorded on 2026-02-10 at 17:00 UTC, so the data reflect a single moment rather than an ongoing series.

For each pollutant the reported figure is identical across minimum, median and maximum, indicating that only one measurement is available. CO registers 0.29 ppm, NO₂ 0.0089 ppm, O₃ 0.0185 ppm, PM10 33.0 µg/m³, PM2.5 23.0 µg/m³ and SO₂ 0.0014 ppm. Because there is no spread in the numbers, the dataset cannot describe variability or trends within the city; it simply provides a snapshot of conditions at the 무안읍 location at the stated time.

The coverage is therefore limited: one station supplies all six pollutant readings, and the freshness of the data is uniform, with every value updated within the last seven days. Users should keep in mind that air quality can differ across neighborhoods and over short periods, so this single‑point snapshot may not represent conditions elsewhere in Muan or at other times of day.

Data notes

The current dataset for Muan includes six valid measurements and is marked as Updated within 3 days, with the latest values recorded at 2026‑02‑10T17:00:00+00:00. This snapshot reflects conditions at a specific time and location; air quality can differ across neighborhoods and throughout the day, so individual experiences may vary from the reported figures.
