What the data includes

The dataset for Yangpyeong‑gun contains measurements of six key pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), ozone (O₃, written as O3), particulate matter 10 µm or smaller (PM10), fine particulate matter 2.5 µm or smaller (PM2.5, written as PM25) and sulfur dioxide (SO₂). These values come from a total of twelve data rows collected at two monitoring stations, all recorded on the same day: 2026‑02‑10 18:00 UTC. Because every pollutant entry shares this timestamp, the information is uniformly fresh, falling within the “updated within 7 days” category.

Across the twelve rows the observed concentrations show a fairly narrow spread for each gas and particle type. CO ranges from 0.52 to 0.53 ppm with a median of 0.525 ppm; NO₂ varies between 0.0192 and 0.0208 ppm, centering on 0.02 ppm; O₃ is recorded between 0.008 and 0.0093 ppm, median 0.00865 ppm. Particulate matter shows a broader but still limited range: PM10 values lie from 63 to 68 µg/m³ (median 65.5 µg/m³) while PM2.5 spans 48 to 57 µg/m³ (median 52.5 µg/m³). SO₂ is the lowest‑level gas, recorded between 0.0027 and 0.0029 ppm with a median of 0.0028 ppm.

The data set provides complete coverage for all six pollutants at both stations, but the limited number of monitoring locations means that spatial variation within Yangpyeong‑gun is not captured in detail. All measurements are recent, yet because they come from only two sites, conditions can differ across neighborhoods and times not represented by this snapshot.

Data notes

The dataset for Yangpyeong‑gun includes twelve valid measurements and is updated within three days, with the most recent data recorded at 2026‑02‑10T18:00:00+00:00. This information reflects a single snapshot in time; air quality can differ across neighborhoods and change throughout the day, so conditions you experience may not exactly match these values.
