Air quality today
The air quality in Miryang‑si is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 27.0 µg/m³ and a PM10 level of 29.0 µg/m³, based on six valid observations collected through OpenAQ.
These values reflect the present state of ambient air in the city without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Miryang‑si contains a single monitoring location, identified as 내일동, and provides recent measurements for six key pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5, written as PM25), and sulfur dioxide (SO₂). All six rows were last updated on 2026‑02‑10 at 18:00 UTC, which places every record within the past seven days, indicating that the information is current for the city.
Across the pollutants the reported values are uniform because each metric has only one observation. CO registers at 0.31 ppm, NO₂ at 0.0183 ppm, O₃ at 0.019 ppm, PM10 at 29.0 µg/m³, PM2.5 at 27.0 µg/m³, and SO₂ at 0.0035 ppm. Because there is a single data point per pollutant, the minimum, median, maximum, 10th percentile and 90th percentile are all identical for each substance. This means the dataset does not show any spread or variability within Miryang‑si; it simply reflects the conditions at one site on one recent occasion.
The coverage therefore is limited to a single monitoring station, which captures only a snapshot of air quality rather than city‑wide patterns. While the timestamps are fresh, the lack of multiple stations or repeated measurements means that spatial and temporal variations across Miryang‑si cannot be assessed from this dataset alone. Users should keep in mind that conditions may differ in other neighborhoods or at other times.
