Omsk's air quality reflects the flat West Siberian Plain's Irtysh River position at 85 metres, with vehicle traffic on surrounding roads and the oil refining — Omsk hosting Russia's second largest refinery — petrochemical, and manufacturing corridor generating elevated industrial SO₂ and PM2.5. The flat Siberian plain allows reasonable summer dispersal, while winter residential heating and the extraordinary refinery complex under severe anticyclonic inversions maintain Omsk among Russia's more persistently petroleum industrial-challenged Siberian city environments.

When is air pollution at its worst in Omsk?
Air quality in Omsk tends to be worse when road traffic, steel, cement, and chemical production, and light manufacturing build up and windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Coal and wood used for winter heating add substantially to particulate levels.
Are air quality levels in Omsk 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.
