Air quality today
The air quality in Andong‑si is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 26.0 µg/m³ and a PM10 level of 45.0 µg/m³, based on six valid observations reported through OpenAQ.
These values reflect the present monitoring results for the city. 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 Andong‑si air quality dataset currently contains a single monitoring location, 명륜동, which reports six 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 six measurements were last refreshed on 2026‑02‑10 at 17:00 UTC, meaning every value is less than seven days old; none of the rows are marked as “today” or older than a month. Because there is only one station contributing data, the coverage reflects conditions at that specific neighbourhood rather than the whole city.
The reported values show no variation within each pollutant’s record: CO is consistently 0.96 ppm, NO₂ stays at 0.03 ppm, O₃ at 0.009 ppm, PM10 at 45 µg/m³, PM2.5 at 26 µg/m³, and SO₂ at 0.0025 ppm. The median, minimum and maximum for every pollutant are identical, indicating a single snapshot rather than a range of observations over time. This uniformity means the dataset cannot illustrate short‑term fluctuations or spatial differences across Andong‑si.
Overall, the data set offers a concise but limited picture: it includes all six standard air‑quality gases and particles, is fully up‑to‑date for the last seven days, yet consists of only one recent record from a single site. Consequently, while the numbers give an immediate sense of current concentrations at 명륜동, they do not capture broader city‑wide patterns or day‑to‑day changes.

Data notes
The data shown for Andong‑si is based on six valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T17:00:00+00:00. This snapshot reflects conditions measured at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
