Ibaraki in Osaka reflects the Osaka metropolitan area's northern Ibaraki River position adjacent to Takatsuki, with vehicle traffic on surrounding roads and the manufacturing, university, and residential corridor contributing local sources. Osaka Bay breezes provide limited maritime ventilation, while the broader Kinki metropolitan regional background and summer photochemical ozone from the vast metropolitan corridor maintain moderate Osaka northern metropolitan suburban readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Ibaraki right now?
On 16 July 2026, overall air quality in Ibaraki is poor. AQI is the main air quality indicator at 71.7/100. Pollution peaks around 2:00 PM (O3: 71.7/100).
Will air quality be worse tomorrow in Ibaraki?
On 17 July 2026, air quality conditions in Ibaraki will be worse than today, with AQI forecast at very poor at 89.1/100. Pollution peaks around 4:00 PM (O3: 89.1/100).
When is air pollution at its worst in Ibaraki?
Ibaraki usually sees its poorest air quality when road traffic, petrochemical and refining operations, along with manufacturing activity coincide with periods when summer heat and strong sunlight build up. Photochemical reactions in the heat push ozone levels higher. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Ibaraki based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
