Air quality today

The air quality today in Boryeong‑si is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 37.0 µg/m³, while PM10 stands at 43.0 µg/m³ based on twelve valid observations.

Data are shown via OpenAQ and reflect the current 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 Boryeong‑si air‑quality feed contains 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). All of these values come from a single monitoring location identified as 주교면, so the dataset represents one station row for each pollutant.

The most recent observations were all recorded at the same moment, 2026‑02‑10 18:00 UTC, meaning the data are fresh within the last seven days. CO is reported at 0.51 ppm, NO₂ at 0.009 ppm, O₃ at 0.0128 ppm, PM10 peaks at 43.0 µg/m³, PM2.5 starts at 37.0 µg/m³ and SO₂ reaches 0.0043 ppm. Across the pollutants the recorded ranges are narrow: CO varies between 0.51 and 0.52 ppm, NO₂ from 0.009 to 0.0195 ppm, O₃ from 0.0099 to 0.0128 ppm, PM10 from 41 to 43 µg/m³, PM2.5 from 37 to 40 µg/m³ and SO₂ from 0.0025 to 0.0043 ppm. Median values sit close to the lower ends of these spans (for example, the median CO is 0.515 ppm and the median PM10 is 42 µg/m³), indicating that most recent readings are clustered near the minimum observed levels.

Because the dataset relies on a single site, spatial coverage across Boryeong‑si is limited; conditions can differ in other neighborhoods or at different times of day. Nevertheless, the uniform timestamp shows that every pollutant was captured simultaneously, providing a consistent snapshot of the city’s air quality at that moment.

Data notes

The data shown for Boryeong‑si is based on twelve valid measurements and was refreshed within three days, with the most recent update recorded at 2026‑02‑10T18:00:00+00:00. This snapshot reflects conditions captured across the monitoring network at that time; however, air quality can differ by specific location and moment within the city, so values may vary locally.
