Prayagraj's air quality reflects the Ganga-Yamuna confluence position in the flat Indo-Gangetic Plain at 98 metres, with vehicle traffic on surrounding expressways and industrial, brick kiln, and Kumbh Mela event operations generating elevated PM2.5. The dry winter northeast monsoon concentrates emissions extensively, while the flat alluvial plain's minimal topographic dispersal maintains Prayagraj among northern India's more persistently challenged Gangetic Plain metropolitan environments, particularly during the October to March dry season.

When is air pollution at its worst in Prayagraj?
In Prayagraj, traffic emissions as well as manufacturing activity are the main local sources, with conditions worsening when windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Rains during the wetter months typically wash pollutants out of the air.
Are air quality levels in Prayagraj 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.
