Samarinda's air quality reflects the flat East Kalimantan Mahakam River delta position, with vehicle traffic and the coal mining, palm oil, and vehicle density corridor generating elevated PM2.5. The Makassar Strait provides limited maritime ventilation, while transboundary haze from Kalimantan peatland fires represents the most severe seasonal concern and Samarinda generally maintains moderate to elevated Indonesian Borneo coal capital readings throughout most of the year.

When is air pollution at its worst in Samarinda?
In Samarinda, vehicle traffic and mining and quarrying operations are the main local sources, with conditions worsening when maritime winds die down. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. Fuel burned for winter heating adds an extra layer of particulates on top of other sources.
Are air quality levels in Samarinda 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.
