In Eumseong the air is moderate right now (approximate, US EPA scale). From 18:00 to 04:00 local time the city mean PM2.5 fell from 34.7 to 28.3 µg/m³. The highest hour was 01:00 with 41.3 µg/m³.
Light wind (2 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). Cold weather (4°C) possibly means more heating, a common source of particles.
Weather now: clear, 4°C, wind 2 m/s, humidity 97%. No major change in the wind is expected in the coming hours. By 18:00 the temperature will be about 11°C.

Fresh data for Eumseong are insufficient (last update: 09:45 local time, 00:45 UTC). Open the map for the latest readings of individual sensors.
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.
