Air quality today

The air quality in Yeongwol‑eup is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 31.0 and a PM10 reference value of 40.0, based on six valid observations collected via OpenAQ.

Data indicate that the particulate matter concentrations are within the range described by these reference values. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Yeongwol‑eup contains measurements for six common air pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). All six pollutant types are represented, but the data come from a single monitoring location in 영월읍, so there is only one row of values for each contaminant.

Each pollutant record shows a single observed value that also serves as the minimum, median and maximum for the recent period. CO registers at 0.66 ppm, NO₂ at 0.0158 ppm, O₃ at 0.0147 ppm, PM₁₀ at 40.0 µg/m³, PM₂.₅ at 31.0 µg/m³ and SO₂ at 0.001 ppm. Because the minimum, median and maximum are identical, there is no spread in the reported numbers; the data describe a single snapshot rather than a range of observations.

All six measurements were last updated on 2026‑02‑10 at 18:00 UTC, which falls within the “updated within 7 days” freshness category. This means the most recent readings are relatively current, but because only one timestamp is available for each pollutant, the dataset does not capture variability over time or across different parts of Yeongwol‑eup. Consequently, while the figures give a clear picture of the latest recorded levels at that specific site, they do not reflect possible changes elsewhere in the town or any short‑term fluctuations that might occur between updates.
