Seremban's air quality reflects the Negeri Sembilan Linggi River valley position in the Malaysian central highlands at 60 metres, with vehicle traffic on the North-South Expressway and surrounding manufacturing, palm oil, and government corridor contributing local sources. The Titiwangsa Range provides topographic variation, while transboundary haze from Indonesian peatland fires represents the primary severe seasonal concern and Seremban generally maintains moderate Malaysian central corridor readings throughout non-haze periods.

When is air pollution at its worst in Seremban?
In Seremban, traffic on the surrounding roads and textile and manufacturing operations are the main local sources, with conditions worsening when winds are light and dispersion is poor. Background emissions and local weather both shape how conditions change from day to day. Local weather patterns add further day-to-day variation.
Are air quality levels in Seremban 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.
