Ipoh's air quality reflects the Kinta River valley's dramatic limestone karst enclosure between the Titiwangsa and Keledang ranges in Perak, with vehicle traffic on the North-South Expressway and surrounding mining legacy, manufacturing, and residential character contributing local sources. The limestone karst valley creates distinctive topographic enclosure, while transboundary haze from Indonesian peatland fires is the primary severe seasonal concern and the karst valley's limited dispersal under calm conditions creates occasional concentration episodes throughout the year.

When is air pollution at its worst in Ipoh?
Air quality in Ipoh tends to be worse when traffic on the surrounding roads, mining and quarrying operations, along with manufacturing activity build up and still air allows pollutants to build up. Local weather patterns add further variation on top of these sources. Background emissions and local weather both play a role in day-to-day changes.
Are air quality levels in Ipoh 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.
