In Taean the air is moderate right now (approximate, US EPA scale). From 18:00 to 04:00 local time the city mean PM2.5 rose from 10.7 to 14.0 µg/m³. The highest hour was 21:00 with 19.3 µg/m³.
Light wind (1 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). High humidity (86%) possibly makes optical sensors read somewhat higher.
Weather now: partly cloudy, 9°C, wind 1 m/s, humidity 86%. By 08:00 the wind is expected to pick up to 4 m/s, which may clear the air. By 18:00 the temperature will be about 13°C.
