In Goyang the air is moderate right now (approximate, US EPA scale). From 18:00 to 04:00 local time the city mean PM2.5 stayed roughly level: from 26.7 to 26.7 µg/m³. The highest hour was 20:00 with 32.0 µg/m³.

Cold weather (5°C) possibly means more heating, a common source of particles. High humidity (99%) possibly makes optical sensors read somewhat higher.

Weather now: partly cloudy, 5°C, wind 3 m/s, humidity 99%. By 14:00 the wind is expected to pick up to 5 m/s, which may clear the air. By 18:00 the temperature will be about 12°C.
