Air quality today
The air quality today in Pyeongchang‑eup is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 43.0 µg/m³, while the accompanying PM10 level stands at 53.0 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 dataset for Pyeongchang‑eup contains measurements for six common air‑quality gases and particles: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10), particulate matter 2.5 µm or smaller (PM2.5) and sulfur dioxide (SO₂). All of these pollutants are represented, but the coverage comes from a single monitoring location – the only station that reported data for this city. In total there are six rows of observations, one per pollutant, each tied to the same site in 평창읍.
Every reading was last refreshed on 2026‑02‑10 18:00 UTC, which falls within the “updated within 7 days” freshness bucket used by OpenAQ. Because all timestamps are identical and recent, the dataset reflects a snapshot rather than an ongoing time series. For each pollutant the reported value is also singular: CO registers at 0.65 ppm, NO₂ and O₃ both sit at 0.0133 ppm, SO₂ at 0.0014 ppm, PM10 at 53.0 µg/m³ and PM2.5 at 43.0 µg/m³. The minimum, median and maximum values are the same for every pollutant, indicating no observed variation within this particular collection period.
These facts lead to a few practical observations. First, the breadth of chemical coverage is complete for the six target pollutants, yet the depth of spatial sampling is limited to one point in the town, so conditions elsewhere may differ. Second, because each pollutant has only a single recorded value, there is no range or spread to describe short‑term fluctuations; the data represent a static picture rather than trends. Finally, the uniform freshness across all measurements means that, as of the latest update, the snapshot is current, but users should be aware that any changes after 2026‑02‑10 are not captured in this set.

Data notes
The data shown for Pyeongchang‑eup is based on six valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10T18:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
