Air quality today
The air quality in Waegwan‑eup is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 27.0 and a PM10 reference value of 33.0, based on six valid observations collected via OpenAQ.
These figures 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 Waegwan‑eup air quality record draws on six sensor rows, each reporting the full suite of measured pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀), fine particulate matter 2.5 µm or smaller (PM₂.₅) and sulfur dioxide (SO₂). All six rows are tied to the same location in Chilgok‑gun, and every pollutant has a single reported value because the minimum, median and maximum values are identical across the dataset.
The most recent data point for each contaminant was recorded on 2026-02-10 17:00 UTC, which falls within the “updated within 7 days” freshness category. Because every pollutant shares this timestamp, the overall picture is uniformly current rather than a mix of old and new entries. No rows are flagged as unknown or missing, so coverage for Waegwan‑eup is complete across all six pollutants.
Because each pollutant appears only once, there is no spread to describe; the values are fixed at 0.32 ppm for CO, 0.0184 ppm for NO₂, 0.0041 ppm for O₃, 33.0 µg/m³ for PM₁₀, 27.0 µg/m³ for PM₂.5 and 0.0022 ppm for SO₂. This uniformity means the dataset provides a snapshot rather than a range of conditions, and any variation in air quality across different parts of Waegwan‑eup or over time would not be captured by these six rows alone.
