Bahār in Iran reflects the Hamadan Province's Alvand Mountain highland position at 1,722 metres, with vehicle traffic and agricultural and services operations contributing local sources. The elevated Zagros plateau position aids dispersal on most days, while winter residential heating under mountain inversions generates seasonal PM2.5 and Bahar generally maintains moderate western Iranian highland plateau readings throughout most of the year.

When is air pollution at its worst in Bahār?
Bahār usually sees its poorest air quality when traffic emissions and agricultural burning coincide with periods when the colder winter months arrive. Fuel burned for winter heating adds an extra layer of particulates on top of other sources. This effect eases considerably during the warmer months.
Are air quality levels in Bahār 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.
