Air quality today
The air quality today in Goseong‑gun is rated as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 18.0 and a PM10 reference value of 24.0, based on six valid observations reported through OpenAQ.
These figures reflect the current assessment for the area without additional interpretation. 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 Goseong‑gun currently consists of a single monitoring location in 고성읍, so every pollutant reading comes from one row of data. All six common pollutants tracked by OpenAQ are present: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10), fine particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO₂). The most recent update for each of these measurements was logged on 2026‑02‑10 at 18:00 UTC, meaning the dataset is fresh within the last seven days for every pollutant.
Across the six substances the reported values show no variation because only one observation exists. CO registers a constant 0.25 ppm, NO2 sits at 0.012 ppm, O3 at 0.0184 ppm, PM10 measures 24.0 µg/m³, PM2.5 records 18.0 µg/m³ and SO₂ is 0.0022 ppm. Because the minimum, median, maximum, 10th‑percentile and 90th‑percentile figures are identical for each pollutant, there is no spread to describe; the dataset reflects a single snapshot rather than a range of conditions.
The limited station coverage means that spatial differences within Goseong‑gun cannot be captured, and temporal changes are not observable beyond this one timestamp. Consequently, while the data are up‑to‑date, they represent only the conditions at 고성읍 on 2026‑02‑10 18:00 UTC. Users should keep in mind that air quality can vary across neighborhoods and over time, so a broader network of sensors would be needed to portray a more complete picture of the county’s atmospheric state.

Data notes
The data shown for Goseong‑gun is based on six valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T18:00:00+00:00. While this snapshot reflects recent conditions across the monitoring network, air quality can differ by specific location and time of day within the city, so values may not represent every neighborhood or moment precisely.
