Ageoshimo in Saitama reflects the flat Saitama Menuma River plain position adjacent to Ageo city north of Tokyo, with vehicle traffic on surrounding roads and the manufacturing and residential character contributing local sources. The flat Kanto Plain allows reasonable dispersal, while the broader Tokyo metropolitan regional emissions elevate background and summer photochemical ozone from the vast Kanto corridor is the primary warm-season concern and the area generally maintains moderate Tokyo northern Saitama suburban readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Ageoshimo right now?
On 17 August 2026, overall air quality in Ageoshimo is fair. O3 is the main pollutant at 34.2/100. Pollution peaks around 8:00 PM (NO2: 42.4/100).
Will air quality be worse tomorrow in Ageoshimo?
On 18 August 2026, air quality conditions in Ageoshimo will be similar to today, with SO2 forecast at fair at 25.0/100. Pollution peaks around 7:00 PM (NO2: 43.4/100).
When is air pollution at its worst in Ageoshimo?
Pollution in Ageoshimo typically rises when traffic on the surrounding roads, heavy industry such as steel, cement, or petrochemical processing, along with light manufacturing combine, especially 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 Ageoshimo 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
