This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Seorak-myeon is classified as USG today. The primary pollutant identified is PM2.5, fine particulate matter that dominates the current assessment. Measurements show a PM2.5 concentration of 54.0 µg/m³ and a PM10 level of 60.0 µg/m³, based on six valid observations recorded through OpenAQ.
These values reflect the latest available data 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 Seorak‑myeon contains a single monitoring site that reports six separate pollutant measurements: 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). Each pollutant is represented by one row, so the total number of rows in the current feed is six. All six observations were recorded at the same timestamp – 2026‑02‑10 18:00 UTC – and are flagged as having been updated within the past seven days.
The values shown are uniform across each pollutant because only a single measurement exists for the site. CO registers at 0.57 ppm, NO₂ at 0.0173 ppm, O₃ at 0.0064 ppm, SO₂ at 0.0022 ppm, PM10 at 60.0 µg/m³ and PM2.5 at 54.0 µg/m³. Because there is no variation among multiple readings, the minimum, median, maximum, 10th percentile and 90th percentile are all identical for each pollutant. This means the dataset does not provide a range or spread of values over time; it offers only a snapshot from one recent moment.
With just one active station, coverage across Seorak‑myeon is limited to that specific location, and the data set lacks older or unknown timestamps that would indicate longer historical records. Consequently, while the current figures are fresh, they represent a narrow spatial and temporal slice of air quality in the area, and conditions elsewhere in the township may differ from what this single point measurement shows.

Data notes
The data shown for Seorak-myeon is based on six valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T18:00:00+00:00. These values represent a snapshot of conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so actual exposure may vary from what is displayed here.
