Pekanbaru's air quality reflects the flat central Sumatra Siak River valley position at 30 metres in the Riau Province, with vehicle traffic on surrounding roads and the palm oil, Chevron petroleum, and vehicle density corridor generating elevated PM2.5. The flat Sumatran terrain allows limited dispersal, while transboundary haze from Riau Province's own extraordinary peatland fires makes Pekanbaru one of Southeast Asia's most severely and frequently peatland haze-affected provincial capitals throughout most dry seasons.

When is air pollution at its worst in Pekanbaru?
The biggest local contributor to pollution in Pekanbaru is road traffic, particularly once winds are light and dispersion is poor. Day-to-day conditions here depend heavily on the weather. Conditions can otherwise vary considerably with the weather.
Are air quality levels in Pekanbaru 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.
