Air quality today

The air quality today in Yeongju‑si is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 38.0 µg/m³. In addition, the PM10 level is recorded at 53.0 µg/m³ based on twelve valid observations.

These values reflect the current monitoring data shown via OpenAQ for Yeongju‑si. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Yeongju‑si air quality feed contains data for six pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO₂). The dataset comprises twelve individual rows drawn from two monitoring stations, all of which reported their most recent values on 2026‑02‑10 at 18:00 UTC, so the information is uniformly fresh within the past week.

Across the city the recorded concentrations show a modest spread. CO ranges from 0.67 ppm to 1.04 ppm with a median of 0.86 ppm; NO₂ stays between 0.02 ppm and 0.0249 ppm, median 0.022 ppm; O₃ varies from 0.0121 ppm up to 0.0189 ppm, median 0.0155 ppm. For the particulates, PM10 values sit between 53 µg/m³ and 57 µg/m³ (median 55 µg/m³) while PM2.5 runs from 38 µg/m³ to 40 µg/m³ (median 39 µg/m³). SO₂ is the lowest‑level gas, recorded between 0.0031 ppm and 0.0066 ppm with a median of 0.00485 ppm.

The data set shows consistent coverage across all six pollutants – each has two recent readings from both stations, so no pollutant is missing or significantly under‑represented. The narrow interquartile ranges (10th to 90th percentiles) indicate that measurements are clustered tightly around their medians, suggesting limited short‑term variability at the sampled locations during the reporting period. Because only two stations contribute, conditions elsewhere in Yeongju‑si may differ from these point values, and any city‑wide assessment should consider spatial variation beyond the current monitoring points.

Data notes

The data shown for Yeongju‑si is based on 12 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 captured by the monitoring network at that time; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
