In Jiujiang the air is moderate 🟡 AQI 90. Higher than three hours ago. ☁️ +11 °C · No precipitation · Wind 1 m/s

In Jiujiang the air is moderate right now (approximate, US EPA scale). From 17:00 to 06:00 local time the city mean PM2.5 rose from 12.8 to 30.3 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 (89%) possibly makes optical sensors read somewhat higher.

Weather now: cloudy, 11°C, wind 1 m/s, humidity 89%. Precipitation is expected around 14:00; it may wash particles out.

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.
