In Namyangju the air is moderate right now (approximate, US EPA scale). From 18:00 to 07:00 local time the city mean PM2.5 fell from 33.8 to 26.0 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: cloudy, 4°C, wind 2 m/s, humidity 99%. By 15:00 the wind is expected to pick up to 4 m/s, which may clear the air. By 18:00 the temperature will be about 11°C.
