Air quality today

The air quality in Boseong‑gun is classified as Good today. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 9.0 µg/m³ and a PM10 reference value of 12.0 µg/m³, based on twelve valid observations collected via OpenAQ.

Overall conditions meet the Good category criteria according to the latest data available for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Boseong‑gun contains measurements of six common air pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀), particulate matter 2.5 µm or smaller (PM₂.₅) and sulfur dioxide (SO₂). All values come from two monitoring stations, together providing twelve recent records. Each pollutant has a most‑recent reading dated 2026‑02‑10 18:00 UTC, and the system flags all of them as “Updated within 7 days,” indicating that the data are current at the time of access.

Across the two sites the observed concentrations span modest ranges. CO varies from 0.25 to 0.49 ppm with a median of 0.37 ppm; NO₂ is between 0.0032 and 0.0066 ppm, median 0.0049 ppm; O₃ shows values from 0.0281 to 0.031 ppm, median about 0.0295 ppm. For the particulates, PM₁₀ ranges from 8.0 to 12.0 µg/m³ (median 10 µg/m³) and PM₂.₅ from 6.0 to 9.0 µg/m³ (median 7.5 µg/m³). SO₂ is the lowest‑level gas, recorded between 0.0019 and 0.002 ppm with a median of roughly 0.00195 ppm.

The data set is fairly compact: only two stations contribute, so spatial coverage within Boseong‑gun is limited to those locations. Nevertheless, every pollutant has at least one recent measurement, and the spread between minimum and maximum values is narrow for each, suggesting relatively stable conditions during the reporting window. Because the dataset does not include older or missing timestamps, it cannot capture longer‑term variations, so readers should keep in mind that air quality can differ across other parts of the county and at times outside the most recent update.
