Air quality today
The air quality in Gui-myeon is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 20.0 µg/m³ and a PM10 level of 21.0 µg/m³, based on six valid observations collected through 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 air‑quality record for Gui‑myeon currently consists of a single monitoring location, so all six listed pollutants are drawn from one set of observations. Carbon monoxide (CO) is reported at 0.29 ppm, nitrogen dioxide (NO₂) at 0.0068 ppm, ozone (O₃) at 0.0158 ppm, sulfur dioxide (SO₂) at 0.0012 ppm, particulate matter ≤10 µm (PM10) at 21 µg/m³ and particulate matter ≤2.5 µg/m³ (PM2.5) at 20 µg/m³. For each pollutant the minimum, median and maximum values are identical, indicating that only one measurement is available for every compound.
All six measurements share the same most‑recent timestamp of 2026‑02‑10 17:00 UTC, which falls within the “updated within 7 days” freshness category. Because there is just one data row, the dataset shows no variation over time or across sites; the reported values represent a single snapshot rather than an ongoing series.
Consequently, while the dataset provides a complete set of common urban pollutants for Gui‑myeon, its coverage is limited to one location and one recent reading. The lack of multiple stations means spatial differences in air quality across the town cannot be assessed from this source, and the uniform timestamps mean no trend information is available. Users should keep in mind that conditions may differ elsewhere or change after the recorded moment, as the current data set does not capture such variability.

Data notes
The data shown for Gui‑myeon is based on six valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10T17:00:00+00:00. This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
