Air quality today
The air quality in Yanggu‑eup is classified as USG today. The primary pollutant identified is PM2.5, with a measured concentration of 41.0 µg/m³. In addition, the PM10 level is recorded at 42.0 µg/m³ based on six valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for this location. 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 Yanggu‑eup air quality dataset currently consists of a single monitoring location, providing one row of data for each of the six measured pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), ozone (O₃, written as O3), particulate matter up to 10 µm (PM10), fine particulate matter up to 2.5 µm (PM2.5, written as PM25), and sulfur dioxide (SO₂). All six pollutants are represented, so the dataset covers the full suite of common urban air‑quality indicators.
The most recent observations for every pollutant were recorded on 2026‑02‑10 at 18:00 UTC, meaning the freshest data are just a few days old. Because there is only one station, each pollutant has a single reported value rather than a range across multiple sites. For CO the reading is 0.65 ppm; NO₂ is 0.0199 ppm; O₃ is 0.0146 ppm; SO₂ is 0.0022 ppm. Particulate concentrations are 42.0 µg/m³ for PM10 and 41.0 µg/m³ for PM2.5. The median, minimum and maximum values are identical for each pollutant, reflecting the single‑row nature of the data.
Given the limited spatial coverage, the dataset cannot capture variations that might exist within different neighborhoods or micro‑environments in Yanggu‑eup. Nevertheless, the timestamps show that all measurements were updated within the last week, providing a recent snapshot of conditions at the monitoring point. Users should keep in mind that air quality can change throughout the day and across the town, so this single set of values represents only the moment and location recorded on 2026‑02‑10 18:00 UTC.
