Mean of 18 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: 23.0 µg/m³; range across sensors: 12.0–33.0 µg/m³.

In Daegu the air is moderate 🟡 AQI 77. About the same as three hours ago. ☁️ +7 °C · No precipitation · Wind 1 m/s

In Daegu the air is moderate right now (approximate, US EPA scale). From 18:00 to 07:00 local time the city mean PM2.5 stayed roughly level: from 21.2 to 22.9 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 (87%) possibly makes optical sensors read somewhat higher.

Weather now: cloudy, 7°C, wind 1 m/s, humidity 87%. No major change in the wind is expected in the coming hours. By 18:00 the temperature will be about 14°C.

Data

Where do these data come from?

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.
