Air quality today
The air quality in Yangyang is currently classified as Moderate. The main pollutant identified is PM2.5, with a measured concentration of 17.0 µg/m³ based on five valid observations.
Data are shown via OpenAQ and reflect the latest available readings 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 Yangyang air‑quality feed draws from a single monitoring site that reports six separate pollutant measurements. The dataset therefore contains one row per pollutant, giving a total of six records for the city. All values were last refreshed on 2026-02-10 at 18:00 UTC, which falls within the “updated within 7 days” freshness bucket, so the information is relatively current across every measured constituent.
The pollutants available are carbon monoxide (CO) at 0.36 ppm, nitrogen dioxide (NO₂) at 0.0066 ppm, ozone (O₃) at 0.0463 ppm, particulate matter ≤10 µm (PM10) reported as 9 999 µg/m³, fine particulate matter ≤2.5 µm (PM2.5) at 17 µg/m³, and sulfur dioxide (SO₂) at 0.0022 ppm. For CO, NO₂, O₃, PM2.5 and SO₂ the minimum, median and maximum values are identical, indicating that only a single measurement is present for each of these gases and particles. In contrast, the PM10 figure stands out as an extreme placeholder value (9 999 µg/m³), suggesting either a sensor malfunction or missing data rather than a true concentration.
Because the dataset consists of just one monitoring location, spatial coverage across Yangyang is limited; conditions elsewhere in the city may differ from those captured at this site. The uniform timestamps show that no older or unknown‑age records are present, but the lack of multiple stations means there is no way to assess temporal variation beyond this single snapshot. Consequently, while the data give a clear picture of the current levels for most pollutants, the PM10 reading should be treated with caution and not interpreted as representative of ambient dust concentrations in Yangyang.

Data notes
The data shown for Yangyang reflects five valid measurements and was updated within 3 days, with the most recent reading recorded at 2026‑02‑10T18:00:00+00:00. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
