Air quality today
The air quality today in Hapcheon‑gun is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 16.0 µg/m³ and a PM10 reference value of 22.0 µg/m³, based on six valid observations recorded by OpenAQ.
These figures indicate the current state of particulate matter in the area without implying any health implications. 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 Hapcheon‑gun includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10), fine particulate matter 2.5 µm or smaller (PM2.5) and sulfur dioxide (SO₂). All values come from a single monitoring location in Hapcheon‑eup, so the station count is one row per pollutant, giving a total of six rows of data.
Each pollutant was last recorded on 2026-02-10 18:00 UTC, which falls within the “updated within 7 days” freshness category. Because every measurement shares the same timestamp, the overall dataset can be described as uniformly recent. The reported numbers show no variation across time or location: CO is consistently 0.34 ppm, NO₂ stays at 0.0109 ppm, O₃ at 0.0147 ppm, PM10 at 22.0 µg/m³, PM2.5 at 16.0 µg/m³ and SO₂ at 0.0021 ppm. For each pollutant the minimum, median, maximum, 10th percentile and 90th percentile are identical, indicating a single data point rather than a range of observations.
Because the coverage is limited to one site, the figures represent conditions only for that specific spot in Hapcheon‑eup at the recorded moment. The lack of multiple stations means spatial variability across the wider county cannot be captured here, and any changes that occur after the last update will not be reflected until a new reading is posted. Consequently, while the data are fresh, they provide a snapshot rather than a comprehensive picture of air quality throughout Hapcheon‑gun.
