Cilacap's air quality reflects the flat Central Java southern coast position on the Indian Ocean, with vehicle traffic on surrounding roads and the Pertamina oil refinery — Indonesia's largest — and cement corridor generating elevated industrial SO₂ and PM2.5. Consistent Indian Ocean maritime breezes provide coastal ventilation, while the refinery's extraordinary industrial scale makes Cilacap Indonesia's most distinctively petroleum refinery-defined coastal industrial environment throughout most of the year.

When is air pollution at its worst in Cilacap?
The biggest local contributors to pollution in Cilacap are traffic on the surrounding roads along with petrochemical and refining operations, particularly once windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Cilacap 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.
