Sekimachi in Gifu reflects the Gifu Prefecture Kisogawa River valley position adjacent to the Nobi Plain, with vehicle traffic on surrounding roads and the light manufacturing and agricultural character contributing modest local sources. The flat Nobi Plain allows reasonable dispersal, while summer photochemical ozone from the Chukyo metropolitan corridor is the primary warm-season concern and the area generally maintains moderate Gifu provincial corridor readings throughout most of the year.

When is air pollution at its worst in Sekimachi?

Sekimachi usually sees its poorest air quality when traffic on the surrounding roads, heavy industrial and chemical processing, together with manufacturing activity coincide with periods when summer heat and strong sunlight build up. Strong sunlight reacting with local emissions drives up ground-level ozone. Cooler temperatures for the rest of the year keep this in check.

Are air quality levels in Sekimachi 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.
