Trichinopoly's air quality reflects the flat Tamil Nadu Kaveri River delta plain at 78 metres, with vehicle traffic on surrounding roads and the vehicle density, manufacturing, and agricultural corridor generating elevated PM2.5. The Bay of Bengal and Arabian Sea monsoon influences provide seasonal ventilation, while the dry season concentrates vehicle and industrial emissions and Tiruchirappalli generally maintains moderate South Indian Kaveri delta metropolitan readings throughout most of the year.

When is air pollution at its worst in Trichinopoly?
Pollution in Trichinopoly typically rises when traffic on the surrounding roads, manufacturing activity, together with crop farming combine, especially once dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. The wet season generally clears the air, while the dry season lets levels build back up.
Are air quality levels in Trichinopoly 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.
