In Gwangju the air is moderate 🟡 AQI 64. Lower than three hours ago. ⛅ +5 °C · No precipitation · Wind 1 m/s

In Gwangju 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 15.5 to 16.3 µg/m³. The highest hour was 01:00 with 20.9 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). Cold weather (5°C) possibly means more heating, a common source of particles.

Weather now: partly cloudy, 5°C, wind 1 m/s, humidity 94%. No major change in the wind is expected in the coming hours. By 18:00 the temperature will be about 13°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.
