Eşfahān's air quality reflects the flat Iranian Zayanderud River valley position at 1,574 metres, with vehicle traffic on surrounding roads and the extraordinary steel, petrochemical, and vehicle density corridor generating elevated PM2.5 and SO₂. The surrounding Zagros and Alborz foothills create significant topographic enclosure, while windblown Kavir Desert dust compounds industrial emissions and Esfahan generally maintains among Iran's more severely industrial-influenced provincial capital environments throughout most of the year.

When is air pollution at its worst in Eşfahān?
In Eşfahān, traffic on the surrounding roads as well as steel, cement, and chemical production are the main local sources, with conditions worsening when windblown dust events occur. Dust carried on these winds adds substantially to particulate levels. Such events are most common in the drier shoulder seasons.
Are air quality levels in Eşfahān 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.
