Delhi's air quality reflects the flat Indo-Gangetic Plain's Yamuna River position at 216 metres surrounded by the Aravalli and Shivalik ranges, with vehicle traffic on the surrounding ring roads and the extraordinary vehicle density, crop stubble burning from Punjab and Haryana, brick kilns, and industrial corridor generating some of the world's most severe sustained PM2.5. The flat alluvial plain's minimal topographic dispersal and the October to March dry northeast monsoon create catastrophic winter concentration episodes, maintaining Delhi as one of the world's most severely and persistently challenged major capital city air quality environments throughout the year.

When is air pollution at its worst in Connaught Place?
Delhi usually sees its poorest air quality when traffic on the surrounding roads, textile and manufacturing operations, as well as agricultural burning coincide with periods when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Rainfall through the monsoon usually keeps levels in check.
Are air quality levels in Connaught Place 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.
