Daily mean PM2.5 on November 10, 2026 (00:00–24:00 UTC = 09:00–09:00 UTC+9): 19 µg/m³ from 5 sensors that passed the quality check — the same value as in the Atmy Data Hub. No. 3 of 39 cities in South Korea and No. 344 of 676 worldwide, from the most polluted.
Right now in Dangjin, PM2.5 averages 35.0 µg/m³ — “moderate” on the US EPA scale (approximate, from hourly readings). Mean of 4 sensors from Government stations, readings from 06:00–06:00 local time (21:00–21:00 UTC), summary prepared at 07:00 local time. Median: 27.5 µg/m³; range across sensors: 20.0–65.0 µg/m³.
The current level is “moderate” (US EPA scale, approximate). Unusually sensitive people should consider reducing prolonged or heavy exertion outdoors. This is the standard guidance of the scale, not medical advice.
Highest current reading: 65.0 µg/m³ (평택당진항 (한국환경공단 에어코리아 (AirKorea))). Lowest: 20.0 µg/m³ (당진시청사 (한국환경공단 에어코리아 (AirKorea))). The list shows every sensor, highest first.
From Atmy sensors and connected public networks (citizen, experimental and government monitors), aggregated by Atmy. Values are approximate; see the methodology.
The summary is rebuilt every 15 minutes from the latest reading of each sensor, each no older than one hour.
The daily value is the Data Hub’s: the mean of the city’s sensors that passed the nightly quality check, each with at least 12 valid hours, and only with sensors at four places 500 m apart; days are UTC.
“Now” uses the same sensors and rule: the mean of their latest readings, each at most 60 minutes old, shown only with sensors at four places 500 m apart reporting.
