Mean of 13 sensors from Government stations, readings from 05:00–05:00 local time (20:00–20:00 UTC), summary prepared at 07:00 local time. Median: 14.0 µg/m³; range across sensors: 8.0–24.0 µg/m³.

In Osaka the air is moderate 🟡 AQI 60. Higher than three hours ago. ☀️ +9 °C · No precipitation · Wind 1 m/s

In Osaka the air is moderate right now (approximate, US EPA scale). From 18:00 to 07:00 local time the city mean PM2.5 rose from 6.8 to 14.0 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 (85%) possibly makes optical sensors read somewhat higher.

Weather now: clear, 9°C, wind 1 m/s, humidity 85%. No major change in the wind is expected in the coming hours. By 18:00 the temperature will be about 17°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.
