Shibukawa's air quality reflects the flat Gunma Prefecture Tone River plain position at the Haruna Mountain base, with vehicle traffic on surrounding roads and the hot springs, manufacturing, and services corridor contributing local sources. The flat Kanto Plain generally allows reasonable dispersal, while the Foehn-like Oroshi winds and summer photochemical ozone from the Kanto corridor are the primary warm-season concerns and Shibukawa generally maintains moderate Japanese inland Gunma plain readings throughout most of the year.

When is air pollution at its worst in Shibukawa?
The biggest local contributors to pollution in Shibukawa are vehicle traffic, steel, cement, and chemical production, together with manufacturing activity, particularly once hot, still weather settles in. Strong sunlight reacting with local emissions drives up ground-level ozone. This is far less of an issue outside the warmer months.
Are air quality levels in Shibukawa 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.
