Belāhi's air quality reflects the flat Bihar Indo-Gangetic Plain position, with vehicle traffic on surrounding roads and agricultural, brick kiln, and small manufacturing operations contributing local sources. The dry winter northeast monsoon concentrates brick kiln and vehicle emissions extensively, while the flat alluvial plain's minimal topographic dispersal maintains elevated winter readings and the Bihar regional airshed's industrial and biomass burning background compounds local sources throughout the year.

When is air pollution at its worst in Belāhi?
The biggest local contributors to pollution in Belāhi are road traffic, light manufacturing, along with farming and agricultural processing, particularly once dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Rains during the wetter months typically wash pollutants out of the air.
Are air quality levels in Belāhi 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.
