Air quality today
The air quality in Yecheon‑gun is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 28.0 µg/m³ and a PM10 level of 35.0 µg/m³, based on six valid observations collected through OpenAQ.
These values reflect the present conditions without implying any trend or cause. 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 Yecheon‑gun air‑quality dataset currently contains six individual monitoring rows, each reporting a single set of values for the six pollutants tracked in this city: 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 rows were last refreshed on 2026‑02‑10 at 18:00 UTC, which places the data comfortably within a seven‑day freshness window.
Because each pollutant is represented by only one measurement point, the reported figures show no internal variation – the minimum, median and maximum values are identical for every substance. CO registers at 0.31 ppm, NO₂ at 0.0084 ppm, O₃ at 0.0252 ppm, PM₁₀ at 35.0 µg/m³, PM₂.₅ at 28.0 µg/m³ and SO₂ at 0.0024 ppm. This uniformity means the dataset does not capture spatial or temporal spread within Yecheon‑gun; it provides a single snapshot rather than a range of conditions across different locations or times.
The overall coverage is therefore limited to one recent reading per pollutant, with no older or unknown timestamps in the current set. While this offers an up‑to‑date picture for the moment captured on 2026‑02‑10, it also means that variations throughout the day or across the wider county are not reflected. Users should keep in mind that air quality can differ by neighbourhood and over shorter intervals than those represented here.
