Air quality today

The air quality in Gangneung‑si is currently assessed as Moderate, with PM2.5 identified as the main pollutant.

Measurements from 24 valid observations show a PM2.5 reference value of 25.0 µg/m³ and a PM10 reference value of 34.0 µg/m³, as reported by OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Gangneung‑si’s OpenAQ feed contains data for six common air pollutants – 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). The dataset is built from 24 individual measurement rows, each representing a separate sensor reading taken at the same location, 초당동, on 2026‑02‑10 at 18:00 UTC. All of these entries are flagged as “Updated within 7 days,” indicating that the most recent observations for every pollutant are less than a week old.

The recorded values show modest variability across the pollutants. CO ranges from a low of 0.21 ppm to a high of 0.33 ppm, with a median around 0.31 ppm; NO₂ spans 0.0047‑0.0108 ppm (median ≈0.0073 ppm); O₃ varies between 0.0355 and 0.051 ppm (median ≈0.049 ppm). For the particulate fractions, PM10 values are between 13 µg/m³ and 34 µg/m³, with a typical concentration near 17.5 µg/m³, while PM2.5 ranges from 9 to 25 µg/m³ (median ≈11.5 µg/m³). SO₂ is the lowest‑concentration gas, recorded from 0.0014 to 0.0025 ppm (median ≈0.0018 ppm).

Because every pollutant in this city’s feed comes from a single monitoring site and shares the same timestamp, coverage across pollutants is uniform but spatially limited; there are no additional stations providing alternative locations or times. The dataset therefore reflects conditions at one point in time rather than a broader city‑wide picture, and readers should keep in mind that air quality can differ by neighborhood and over shorter intervals than the 24‑hour snapshot captured here.

Data notes

The dataset for Gangneung‑si includes 24 valid measurements and is updated within 3 days, with the most recent values recorded at 2026‑02‑10T18:00:00+00:00. These figures represent a snapshot of ambient conditions across the city; actual air quality can differ by specific location and time of day, so users should consider local variations when interpreting the data.
