Kermānshāh's air quality reflects the western Iranian Zagros Mountain valley at 1,319 metres surrounded by the Alvand and Shahu ranges, with vehicle traffic on surrounding roads and the oil refinery, petrochemical, and vehicle density corridor generating elevated PM2.5 and SO₂. The Zagros valley's topographic enclosure creates concentration under winter inversions, while windblown Iraqi steppe dust compounds industrial emissions and Kermanshah generally maintains among Iran's more challenged western highland provincial capital environments throughout the year.

Frequently Asked Questions
Is air quality bad in Kermānshāh right now?
On 21 September 2026, overall air quality in Kermānshāh is poor. AQI is the main air quality indicator at 78.3/100. Pollution peaks around 8:30 AM (PM10: 78.3/100).
Will air quality be worse tomorrow in Kermānshāh?
On 22 September 2026, air quality conditions in Kermānshāh will be better than today, with AQI forecast at moderate at 45.8/100. Pollution peaks around 11:30 PM (PM10: 45.8/100).
When is air pollution at its worst in Kermānshāh?
Kermānshāh usually sees its poorest air quality when road traffic together with heavy industrial and chemical processing coincide with periods when temperature inversions set in over the valley. The bowl-like terrain here limits how quickly pollutants can escape. Dust carried on these winds adds substantially to particulate levels.
Are air quality levels in Kermānshāh 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.
