Air quality today

The air quality today in Boeun‑gun is classified as USG. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 37.0 µg/m³ and a PM10 concentration also at 37.0 µg/m³, based on six valid observations collected via OpenAQ.

These values reflect the current monitoring data for the area. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Boeun‑gun includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), fine particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO₂). All of these values come from a single monitoring site in the town of 보은읍, so the station coverage for the county is limited to one location.

Each pollutant has a single recorded value that also serves as its minimum, median and maximum, indicating no observed variation within the data set. CO registers at 0.51 ppm, NO₂ at 0.0132 ppm, O₃ at 0.0123 ppm, PM10 at 37.0 µg/m³, PM2.5 at 37.0 µg/m³ and SO₂ at 0.0026 ppm. Because the most recent update for every pollutant is timestamped 2026‑02‑10 17:00 UTC, all measurements are fresh, falling within the “updated within 7 days” category.

The uniformity of the data highlights two practical points. First, there is no spread or range to describe temporal changes – each pollutant shows a single point value rather than a distribution across time. Second, with only one monitoring row per pollutant, the dataset does not capture spatial differences that may exist elsewhere in Boeun‑gun; conditions can vary by location and moment even though the current snapshot is recent.

Data notes

The data shown for Boeun‑gun is based on six valid measurements and was refreshed within the past three days, with the most recent update recorded at 2026‑02‑10T17:00:00+00:00. This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
